Input: Consider Input: Paragraph: A nurse prepares a bottle of donated milk for a baby at Son Dureta's Hospital in Palma de Mallorca, Spain March 10, 2006. REUTERS/Dani Cardona The chemical bisphenol A, or BPA, is commonly used in plastic food and beverage containers and in the coating of food cans. Until now, environmental and consumer activists who have questioned the safety of BPA have relied on animal studies. But the study by British researchers in the Journal of the American Medical Association found that among 1,455 U.S. adults, those with the highest levels of BPA were more likely to have heart disease, diabetes and liver-enzyme abnormalities than those with the lowest levels. U.S. Food and Drug Administration officials said they would review the new findings, which were not yet published when the agency issued a draft conclusion in August that BPA is safe at current exposure levels. “We have confidence in the data that we’ve looked at and the data that we’re relying on to say that the margin of safety is adequate,” FDA official Laura Tarantino said at a meeting of experts advising the agency on whether it made the right call. “There are things you can do if you choose to reduce your level of bisphenol A,” Tarantino said. “But we have not recommended that anyone change their habits or change their use of any of these products because right now we don’t have the evidence in front of us to suggest that people need to.”   Panel chairman Martin Philbert declined to say what the committee’s next move would be. BPA is used to make polycarbonate plastic, a clear shatter-resistant material in products ranging from baby bottles to medical devices. BPA can mimic the hormone estrogen in the body. People can consume BPA when it leaches out of the plastic into baby formula, water or food inside a container. Some retailers and manufacturers are moving away from products with BPA. Canadian officials have concluded BPA was harmful. Steven Hentges of the American Chemistry Council, an industry group, said the study’s design did not allow for anyone to conclude BPA causes heart disease and diabetes. “On the other hand, though, bisphenol A has been very intensively studied in a very large number of laboratory animal studies. And the weight of evidence from those studies ... continues to support the safe use of products containing bisphenol A,” he said in a telephone interview. The British researchers, who acknowledged their findings are not proof that the chemical is causing the harm, analyzed urine samples from a U.S. government health survey of adults ages 18-74 representative of the U.S. population. The 25 percent of people with the highest levels of bisphenol A in their bodies were more than twice as likely to have heart disease, including heart attacks or type 2 diabetes, compared to the 25 percent with the lowest levels. At the FDA panel meeting, several scientists and activists said the FDA ignored animal studies finding health concerns and some called for the chemical to be banned in food containers. Democratic U.S. Rep. John Dingell of Michigan, who heads the House Committee on Energy and Commerce, said the FDA has “focused myopically on industry-funded research.”   Iowa Republican Sen. Chuck Grassley, ranking member of the Committee on Finance, released a letter he wrote to FDA Commissioner Dr. Andrew von Eschenbach asking why the agency has not appointed a safety panel to review BPA. Tarantino said nothing was ignored but industry-funded studies finding no harm were important in the conclusions. The panel is expected to present its advice to the FDA next month. Tarantino, head of the FDA’s office of food additive safety, said there is talk of government scientists doing their own BPA safety studies, but that could take years to conduct. Claim: Common plastics chemical linked to heart problems.

Output: A major study links a chemical widely used in plastic products, including baby bottles, to health problems in humans like heart disease and diabetes, but U.S. regulators said on Tuesday they still believe it is safe.


Input: Consider Input: 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

Output: "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."


Input: Consider Input: Paragraph: The air quality index, measuring levels of PM 2.5, tiny particulate matter in the air, deteriorated to above 900, way over the 500-level that qualifies as “severe-plus”. Aside from the harm it was doing to the lungs of some 40 million people living in the capital region, the smog was so bad more than 30 flights were diverted from Delhi airport due to poor visibility. Roads looked deserted as large numbers of people stayed home, rather than expose themselves to the noxious atmosphere outside. “Pollution has reached unbearable levels across north India,” Arvind Kejriwal, Delhi’s chief minister said in a message on twitter. The government environment monitoring agency SAFAR warned that no relief was expected for the next one to two days, as humidity resulting from unexpected light rains overnight had exacerbated pollution, already driven by higher the seasonal crop stubble burning by farmers in the surrounding states. “Wind speed is picking up and it could take 24 to 48 hours before the pollution level reduces to a level of around 500,” Mahesh Palawat, vice president of Skymet, a private weather forecasting agency, said. Anything above 400 on the AQI poses a risk for people with respiratory illness and can also affect even those with healthy lungs. Doctors were reporting a spike in patients with respiratory related issues, according to Sachin Taparia, head of Local Circles, a Delhi-based private consultancy that conducts surveys on government policies and programs. “Delhi has turned into a gas chamber as the pollution levels hit the ‘severe+’ category,” Taparia said. A survey of 17,000 people in the Delhi region by his consultancy found that 40% want to get out of the Delhi region because of the failure to control pollution. Authorities in Delhi on Friday declared a public health emergency and closed schools and all construction activity. From Monday, the city government will also restrict the use of private vehicles on the capital’s roads under an “odd-even” scheme based on license plates. “The temporary restrictions on private vehicles will have a negligible impact as we face the most hazardous situation,” said Skymet’s Palawat. Delhi’s Kejriwal, and the chief ministers from the neighboring states of Punjab and Haryana, urged the federal government to do more to combat the pollution. On Monday, according to a lawyer, the Supreme Court is likely to hear a petition on Monday from the environment agency, looking for ways to make state governments to take tougher action against farmers to curb the stubble-burning. Politicians have been reluctant to upset their farming constituencies. According to SAFAR, satellite pictures had captured more than 3,000 incidents of stubble burning last week in neighboring states, contributing to 44% of Delhi’s pollution. Claim: India's smog-bound capital suffers most hazardous air so far this year.


Output: Air pollution in New Delhi and surrounding towns reached the worst levels so far this year on Sunday, with authorities in the world’s most polluted capital city having already declared a public health emergency and ordered the closure of schools.
