[EX Q]: Paragraph: "This is the only of the five stories to actually put a dollar figure on the classes. ""Even the cost of a class, which can top $50 a month, is modest compared with the cost of many medications. And unlike drugs, tai chi had no harmful side effects, she says."" Unlike the AP story, which made the mistake of saying that ""symptoms improved significantly for the tai chi group and little for the others,"" this story, at least, presents some numbers. The trouble is, those numbers are in relative terms. So, instead of saying that three months after the classes ended, 27 patients who took tai chi classes felt better and 17 who tried other therapies also felt better, it presents the difference as 82% versus 53%. That seems more dramatic. Absolute data would be more meaningful. Why make the reader do the math? The story is one of the few stories that covered this study to actually point out that ""unlike drugs, tai chi had no harmful side effects."" In the end, because of the comments from Gloria Yeh, the story puts the appropriate caveats on the findings. This sentence does a great job of summarizing some of the problems with the study: ""Yeh notes that researchers don’t know which aspects of tai chi were most helpful: the exercise, deep breathing, relaxation exercise, meeting new friends or learning from a charismatic teacher."" This story actually spends too little time talking about the condition itself. The AP devoted a whole paragraph in an eight paragaph story to the condition, and the LA Times led its piece by describing the disease. USA Today instead went with a very nice description of tai chi, putting the emphasis on the beauty and simiplicity of the therapy rather than the difficulty clinicians have had correctly diagnosing and treating fibromyalgia. This is the only story to include the phrase ""white crane spreads its wings"" or anything like that. The story doesn’t actually quote any of the authors and instead quotes two outside experts, one of whom wrote an accompanying editorial. It fails to fully attribute the comments made by ""Callahan."" It appears that the writer means Leigh F. Callahan, who just completed a study of tai chi for arthritis and was quoted by other reporters. (How did this slip through copy editing? Was this a slip-up only in the online version?) But we can’t give credit to an independent source that the story doesn’t adequately identify. The story does not compare the therapy to existing alternatives or even discuss existing alternatives, aside from a passing reference at the very end to medications. This is the only one of the five stories to note that ""A study in 2007 from the National Institutes of Health found that 2.3 million American adults had used tai chi in the past year."" This doesn’t tell you whether tai chi classes are as readily available in Oklahoma as they are in New Mexico, but it does give you a sense of how popular they are. It is unclear from this story whether tai chi has been studied before for other conditions. It has. It also is unclear what fibromyalgia patients now do for therapy. The LA Times, for example, pointed out that patients in the study stopped taking drugs for treatment, for example. The story does not rely on a news release." Claim: Tai chi may ease fibromyalgia pain
[EX A]: "The story does two things better than all the other stories. It puts a dollar figure to the cost of tai chi therapy, and it gives people a better sense of how popular tai chi is. It could have done a better job evaluating the evidence and providing some absolute numbers to help readers decide how seriously to take these results. Why not just give the absolute numbers? How many out of how many? Why make the reader do the math? ""79% of tai chi participants said their symptoms had improved, compared with 39% of those in the educational class…Even three months after the classes ended, 82% of tai chi students still felt better, compared with 53% of the comparison group."" Sure, the denominators are in the story but we shouldn’t need to pull out the calculator to figure out 79% of x, vs. 39% of x."

[EX Q]: Paragraph: The idea that the domestic dog descended from the grey wolf was originally established in 1993 using comparisons of wolf and dog mitochondrial DNA. This investigation showed that no other living animal was more closely related to the domestic dog than the grey wolf: “The domestic dog is an extremely close relative of the grey wolf, differing from it by at most 0.2% of [mitochondrial DNA].” Mitochondrial DNA is passed down by the mother (without any genetic contribution from the father) and changes only through random mutations that occur from generation to generation. Scientists use this much smaller and separate DNA sequence to estimate when populations of animals first diverged and to estimate the evolutionary relationships between organisms. By the mid-2000s, new technology allowed scientists to map the much longer DNA sequence found on the chromosomes of wolves and dogs — the genes that actually code for physical traits and behaviors. These studies demonstrated a 99.9% similarity (technically 99.96%) between dog and grey wolf, as covered in a 2007 review paper on the topic: In general, the domestic dog is an extremely close relative of the grey wolf, from which it differs by only ~0.04% in nuclear coding-DNA sequence, and no dog [mitochondrial DNA] sequences have been found that show closer kinship to other canid species. This similarity is so profound that hybridization often occurs between dogs and wolves. By the biological definition of species, this would mean that the domestic dog is a subspecies of the grey wolf (canis lupus familiaris). There remains some debate, however, as to what the appropriate classification for the domestic dog would be, with some arguing that the domestic dog should be its own distinct species (canis familiaris). Claim: Dogs and wolves are genetically 99.9% identical.
[EX A]: These advances in genetic analysis have allowed scientists as well to pin down the probable timing of the split between these two canid lineages. A study published in 2015, which compared the whole genome sequence of dogs to a 35,000 year old Siberian wolf specimen, suggested the split likely occurred between 27,000 and 40,000 years ago, and that domestic dogs are likely themselves the descendants of a now extinct descendant of grey wolves.

[EX Q]: Paragraph: They say government policies are partly to blame for a system in which doctors and other staff expect to be paid extra fees to perform operations and take kickbacks from pharmaceutical firms and medical-equipment suppliers. The profession’s ugly underbelly was exposed last week when police accused British drugmaker GlaxoSmithKline of bribing officials and doctors for six years to boost sales and the price of its medicines. GSK has called the developments “shameful” and on Monday said some of its Chinese executives appeared to have broken the law. China is an appealing market for pharmaceutical firms and medical-equipment makers, with spending in the industry expected to nearly triple to $1 trillion by 2020 from $357 billion in 2011, according to consulting firm McKinsey. The corruption stems largely from doctors’ low base salaries, which are set in line with a pay scale for government workers. Hospitals can pay bonuses but, given public hospitals are strapped for cash, compensation is usually low, say doctors and industry experts. A doctor fresh out of medical school in Beijing earns about 3,000 yuan ($490) a month including bonuses — roughly the same as a taxi driver. A doctor with 10 years experience makes around 10,000 yuan a month, according to Peter Chen, chief executive of privately run Oasis International Hospital in Beijing. “Without the grey income, doctors would not have the incentive to practice,” said Yanzhong Huang, a senior fellow for global health at the Council on Foreign Relations in New York. Over the past 30 years the Chinese government has made its healthcare sector more market-oriented. That means the country’s 13,500 public hospitals have to balance their own books. Medical services accounted for just over 50 percent of public hospital revenue in 2011, according to Health Ministry data. About 40 percent came from prescribing drugs while the rest was from other income as well as government subsidies, which have fallen steadily since the 1980s. Hospital administrators can set fees for in-patient care, nursing and laboratory tests. But the state fixes the cost of operations to make surgery affordable to ordinary Chinese. And it effectively caps the cost of many prescribed medicines by setting a suggested price. That leaves hospitals little room to top up wages. One Chinese doctor who used to hold a senior position at a prominent hospital in Beijing said 80 percent of his income came from bribes. Without it, he would have earned less than $600 a month, said the doctor, who left China five years ago to live in Britain where he continues practicing medicine. “These sums (bribes) are essential. You cannot survive on your salary,” said the 50-year-old physician, who spoke on condition of anonymity due to the sensitivity of the issue. An industry executive who has worked in China’s medical sector for more than 15 years said bribery and corruption permeated every level of a public hospital. “They are seen as necessities in the current healthcare system,” said the executive, who also declined to be identified. The Health Ministry did not respond to a request for comment. Officials at the National Development and Reform Commission, which sets the prices of prescribed medicines, also declined to comment. Low base salaries are a legacy of China’s planned economy, said Jia Xijin, associate professor at the School of Public Policy and Management at Tsinghua University in Beijing, explaining the dilemma faced by the government. China has also committed to making health care affordable for its 1.37 billion people. The government has spent 2.2 trillion yuan ($358 billion) on the system since 2009, of which more than 680 billion yuan was to provide universal health insurance coverage, state media quoted the Finance Ministry as saying earlier this year. Public hospitals say recruiting new doctors is getting harder as many physicians are turned off by the wages at a time when patient numbers are growing. Health Ministry data showed the overall number of doctors rose 13 percent from 2008 to 2011, while patient visits jumped 28 percent. “There will be no doctors left to treat the current doctors when they retire,” said the accounting director at a Shanghai hospital who declined to be identified because she was not authorized to speak to the media. Low salaries have also spawned a system of under-the-table payments from patients. The payments are known as “hongbao” — a reference to the cash-filled red envelopes given as presents during Lunar New Year festivities — and cover various services from jumping the queue for appointments to extra surgical fees. Bob Wang, a 35-year-old businessman in Beijing, said he gave the main surgeon who operated on his aunt’s femur bone transplant last year 5,000 yuan in “hongbao” on top of the 100,000 yuan he paid to the hospital because he was worried the doctor would not take the operation seriously otherwise. There was unstated “hongbao” guidance for each type of surgery, he said. “If my family or myself get sick ... we won’t just go to the hospital. Everything will take forever — from registration to waiting for a bed, to getting seen by a doctor to queuing for surgery,” he said. According to the doctor now living in Britain, patients and their families could sometimes spend two to three times more than the actual fee in “hongbao”. Critics doubt that an anti-corruption campaign by President Xi Jinping will have much impact. Indeed, a former doctor at a major heart hospital in Beijing said eradicating corruption would be nearly impossible. “It would be easy to find out who was taking money if the government wanted to,” said the cardiologist, who has been working in the United States since 2009. “But everyone would be found guilty. How could the hospitals survive?” ($1 = 6.1413 Chinese yuan) Claim: Bribery serves as life-support for Chinese hospitals.
[EX A]:
Bribery is the lubricant that helps keep China’s public hospitals running, and the health system would struggle to function without illegal payments to poorly paid doctors and administrators, say medical practitioners and industry experts.
