Input: Consider Input: Paragraph: The article states that acupuncture costs $45 to $100 per session. It does not say how this compares to other treatments and whether the cost of care is the same, more or less than alternatives. The story states the proportion of patients who successfully responded to each therapy, and clearly explains that "real" acupuncture was no better than sham needling. But it does not define success or otherwise quantify how much people improved clinically in either relative or absolute terms. For a treatment to be considered successful, a patient must have reported either a 33% improvement in pain or as little as a 12% improvement in function during an interview conducted over the telephone 6 months after enrollment. Nonethless we'll grade this criterion as satisfactory. The story did not mention harms from any of the treatments patients received. Previous research suggests that acupuncture poses few risks when performed with sterile, disposable needles. The article describes the largest randomized controlled trial to date investigating the effectiveness of acupuncture for treating chronic low back pain, and reports its published results. It discusses the three treatment groups studied and potential reasons for the outcomes observed. There are no obvious elements of disease mongering. The story explains that the study participants were people with chronic low back pain. These results wouldn't apply to other back pain conditions. The article cites one of the study's coauthors and two physicians who appear to be users and/or proponents of complementary therapies. It would have been interesting to hear from a skeptical observer. The story lists the therapies received by patients assigned to the conventional medicine group. The literature suggests that these treatments generally provide very modest benefits. The article does not mention other therapies that may be effective for managing chronic pain and improving flexibility and strength. These include cognitive therapy alone or in combination with intensive exercise and strengthening. Acupuncture is estimated to be the third most popular complementary therapy for chronic low back pain. Though the article does not say much about its availability, readers are likely to be familiar with it. The story notes that this is the largest study yet of acupuncture for chronic back pain, suggesting that the treatment is not new. There is no obvious use of text from a press release. Claim: Acupuncture, real or fake, called best for lower back pain

Output: This article reports on the largest randomized controlled trial to date investigating the effectiveness of acupuncture for treating chronic low back pain. It explains that both acupuncture and sham needling are more effective than conventional medical therapies, but that "fake acupuncture works nearly as well as the real thing." In addition to describing the quality of the evidence, the story mentions several other treatment options, tells the reader the cost of acupuncture, and hints at its novelty. The story neglects to mention harms. (A recent systematic review reinforces the study's finding that acupuncture poses few risks; see Spine 2005;30:944-63). And it also provides an incomplete picture of the treatment's apparent benefits. Although it notes the proportion of patients who improved with each therapy, it does not define success or otherwise quantify how much people improved clinicallyin either relative or absolute terms. For a treatment to be considered successful, for example, a patient could have reported as little as a 12% improvement in function during an interview conducted over the telephone 6 months after enrollment. This is important information if people are to weigh the apparent benefit of a therapy against its cost. The article cites one of the study's coauthors and two physicians who appear to be users and/or proponents of complementary therapies. They attempt to explain why needling seems to work. To provide some balance, the study's coauthor suggests that the apparent benefit could merely be the result of patients' expectations of improvement from acupuncture, on the one hand, and of poor results from conventional medicine on the other. (Unfortunately, the researchers did not measure patients' expectations.) It would have been interesting to hear from others. Some might point out that the new study shows that acupuncture and sham needling are only more effective than treatments that are not themselves very effective. Others might make the case that acupuncture provides no specific treatment effect and is unethical to usebecause it could be construed as prescribing a placebo. People with chronic low back pain are desperate for anything that will help. When a large new study provides apparently strong evidence to buttress a therapy that previously had little high-quality evidence to support it, readers might also benefit from more context. A major systematic review that analyzed 35 randomized trials involving 2861 patients recently concluded that acupuncture appears to confer modest, short-term pain relief, but that the quality of the studies was not very good. The reviewers were careful not to overstate the benefits of acupuncture (Spine 2005;30:944-63). Overall, this was a good article that would have been helped by some more context.

Input: Consider Input: Paragraph: The deal would resolve alleged violations of civil environmental statutes, including the Clean Water Act, related to the pollution from a company factory in Waynesboro. It would amount to the largest environmental damage settlement in Virginia history and the eighth largest in the nation, officials said. The money would go to projects including wildlife habitat restoration, water quality enhancement and improvements to recreational areas. "In bringing this settlement to a close, we are finally righting a wrong that has impacted the South River and the South Fork of the Shenandoah River for so many decades," Democratic Gov. Terry McAuliffe said at a news conference announcing the settlement. Wilmington, Delaware-based Dupont Co. used mercury in its process of making synthetic fiber at the plant between 1929 and 1950, according to the state Department of Environmental Quality. Strict storage and disposal regulations weren't in place at the time, and some of the mercury seeped into the South River and flowed downstream to the South Fork of the Shenandoah River. DuPont discovered the mercury which accumulates in fish and is especially dangerous to pregnant or breastfeeding women and young children in the facility's soil in 1976, officials say. The pollution impacted over 100 miles of river and thousands of acres of floodplain and riparian habitat, affecting fish, mussels, migratory birds and amphibians, the Department of Justice said in a statement. The pollution also has limited some recreational fishing in Waynesboro, a city of about 20,000 in the Shenandoah Valley. The terms of the settlement are outlined in a proposed consent decree that was filed in federal court in Harrisonburg on Thursday. It is subject to a 45-day public comment period and must be approved by the court. The amount of money proposed is "quite impressive," but mercury is very persistent in the environment and very difficult to remove, said Dr. Thomas Benzing, a professor of integrated science and technology at James Madison University who works with a team of researchers who have been monitoring the mercury levels since 2001. If the settlement goes forward, DuPont would pay slightly more than $42 million toward projects including streamside plantings and erosion control to improve water quality and fish habitat; mussel propagation and restoration; migratory songbird habitat restoration and protection; and recreational fishing access creation or improvement. The company also will pay for renovations at the Front Royal Fish Hatchery to improve production of warm-water fish such as smallmouth bass, at an estimated cost of up to $10 million. "Every dollar is going to be used to clean up the land, the source issues and the water, to where it would have been" if not for the pollution, said Assistant Attorney General John Cruden of the Justice Department's Environmental and Natural Resources Division. No one from DuPont which is awaiting final regulatory approval for its merger with Dow Chemical in a deal to create DowDuPont, a $130 billion conglomerate spoke at the announcement. But Mike Liberati, South River project director for the DuPont Corporate Remediation Group, said in a statement that DuPont "is committed to a long-term presence in the Waynesboro area and to maintaining transparency with its citizens." The first phase of remediation, involving part of the riverbank in Waynesboro's Constitution Park could be complete in February. Soil there containing the highest concentrations of mercury is being excavated and hauled away and replaced by clean topsoil, Liberati said. "It's going to be a long-term project. It's not something that's going to happen overnight," Benzing said. Claim: DuPont to pay $50M over mercury-contaminated Virginia rivers.

Output: Chemical giant DuPont will pay more than $50 million but admit no fault under a proposed environmental settlement after releasing toxic mercury for decades that made its way into Shenandoah Valley waterways, state and federal officials announced Thursday.

Input: Consider Input: Paragraph: On Sunday, the government lifted a ban on travel between cities within Iranian provinces, while restrictions on trips between provinces will end on April 20, state media reported. "45,983 of those infected with the virus have recovered ... There were 1,617 new infected cases in the past 24 hours," Alireza Vahabzadeh, an advisor to Iran's health minister, said on Twitter. Health Ministry spokesman Kianush Jahanpur told Iranian state TV that 3,877 of those infected with the coronavirus were in a critical condition. State TV showed streets packed with people, crowded buses and subway cars in several cities as so-called low-risk businesses - including many shops and workshops - re-opened across Iran from Saturday, with the exception of the capital Tehran, where they will resume activities from April 18. Some health officials and experts have warned the government about a second wave of COVID-19 that they said could hit Tehran hard. Alireza Zali, head of the government-led Coronavirus Taskforce of Tehran, called on people to stay at home. Businesses and services seen as high-risk, including theatres, swimming pools, saunas, beauty salons, schools, shopping centres and restaurants, have yet to re-open. Iran's clerical rulers, who have been struggling to curb the spread of the disease, are concerned that measures to limit public activities could wreck an economy which has already been battered by U.S. sanctions. "We have to fight against the coronavirus and the virus of sanctions together," government spokesman Ali Rabiei said in a televised weekly news conference. Washington reimposed sanctions on Iran in 2018, when U.S. President Donald Trump withdrew the United States from a 2015 nuclear deal with six major powers. Iranian authorities have blamed the sanctions for hampering their efforts to combat the disease. However, Iran's leaders have rejected Washington's offer of humanitarian assistance to contain the coronavirus outbreak. The effect of U.S. sanctions on Iran's new coronavirus response will be remembered by the Iranian people, Iran's Foreign Minister Mohammad Javad Zarif tweeted on Monday. "Despite U.S. sanctions, Iran has made significant progress in fighting the pandemic, thanks to its human & scientific resources, and friends abroad," Zarif wrote. "#Covid19 was (an) opportunity for the U.S. to kick its addiction to sanctions. Instead, it will now live in infamy in the memory of our people." Claim: Iran records 4,585 coronavirus deaths as restrictions eased.
Output: Iran's death toll from the coronavirus outbreak has risen to 4,585, with 111 more overnight, a health ministry official said on Monday, adding the total number of infected cases had reached 73,303 in the most-affected Middle Eastern country
