Input: Consider Input: "The protests against stay-at-home orders in some state capitals have drawn comparisons to the 2010 tea party movement, but the idea of protesting such rules amid a pandemic is not just a 21st-century phenomenon. There are parallels to a protest a century ago. ""During the 1918 Spanish flu pandemic, several influential San Francisco residents including a few physicians formed the Anti-Mask League which objected to wearing masks to prevent the spread of influenza,"" stated an April 22 Facebook post. ""They held meetings of thousands of maskless people. San Francisco was ultimately one of the cities that suffered the most with a high death rate."" (The ""Spanish flu"" is a misnomer — it’s more accurate to refer to it as the flu pandemic of 1918.) The post was flagged as part of Facebook’s efforts to combat false news and misinformation on its News Feed. (Read more about our partnership with Facebook.) The post includes a black-and-white photo of policemen wearing masks over their mouths and noses. We did a reverse Google search and found the image matches a photo of policemen in a different city — Seattle — wearing masks in 1918. But there are accurate statements in the text, which draws from a source at the University of Michigan. We found that there was such a thing as the Anti-Mask League in San Francisco in January 1919. The city did have one of the highest death rates from the flu, but the authors said they can’t prove whether the Anti-Mask League played a role. Mak pulled from an essay by J. Alexander Navarro at the University of Michigan Center for the History of Medicine, a book by Alfred W. Crosby, America’s Forgotten Pandemic and the San Francisco Chronicle archives. As the number of flu cases rose in October 1918 in San Francisco, the city passed an ordinance requiring everyone to wear a mask in public except at mealtime. Mask wearing was promoted as a symbol of patriotism. Gov. William Stephens told Californians it was a ""patriotic duty for every American citizen"" to wear a mask. City officials and local newspapers reported widespread compliance with the mask order initially, Navarro found. But some resisted the rules, and police arrested 110 people on Oct. 27 for not wearing their masks or for failing to keep them properly adjusted. The majority were fined $5, though some went to jail. In November, with cases declining, the city started to lift restrictions, although it still required masks. People flocked to public venues including theaters and sports arenas. At a boxing match, the city’s mayor and city health officer were photographed not wearing masks, for which they were fined. Later that month, the mayor annulled the ordinance. But new cases quickly emerged, and the mask ordinance was reinstated in January. Opponents formed the Anti-Mask League, multiple news articles in January 1919 show. Crosby wrote in his book that the league consisted of ""public-spirited citizens, physicians and fanatics."" At a meeting of the Anti-Mask League ""resolutions were passed denouncing the mask ordinance as contrary to the desires of the majority of the people,"" the San Francisco Examiner reported. Nearly 2,000 people attended. The league got their wish, and the mask rule was rescinded Feb. 1. Navarro and colleagues studied how 43 cities fared during the 1918 pandemic and published their results in the Journal of the American Medical Association. They found that many cities experienced second waves after ending social distancing. San Francisco had one of the higher excess-death rates: 673 per 100,000 people. ""It is impossible to say for certainty that the advent of the Anti-Mask League played a role in that outcome,"" Navarro told PolitiFact ""Undoubtedly, having over 2,000 people gather would have helped continue to spread influenza."" The main factors in San Francisco’s outcome, however, were failure to implement interventions such as social distancing quickly and failure to keep them in place long enough. Navarro said he didn’t find something similar to the Anti-Mask League in other cities. Only a few other cities implemented mandatory face mask orders, while others recommended that the public use masks. A Facebook post said during the 1918 flu pandemic, San Francisco residents formed an ""Anti-Mask League."" San Francisco ""was ultimately one of the cities that suffered the most with a high death rate."" Residents angry about the reinstatement of a mask order did form the Anti-Mask League in January 1919. It appeared to be short-lived, as the mask rule was quickly rescinded. Researchers found that San Francisco did have one of the higher death rates in the country, but it is impossible to say whether that was directly related to the mask protests. A photo of masked police officers that accompanies the post is real, but it shows officers in Seattle."

Output: During the 1918 flu pandemic, San Francisco residents formed the “Anti-Mask League.” San Francisco “was ultimately one of the cities that suffered the most with a high death rate.”


Input: Consider Input: Since this story doesn’t make claims about efficacy, costs don’t seem applicable. We give this story a satisfactory score, but the story could have helped readers understand why measuring surrogate markers such as homocysteine levels can be different than tracking true outcomes such as heart attack or stroke. Here, the surrogate endpoint (homocysteine levels) “improved,” but the real endpoint – heart attack and stroke – did not. There is no discussion of any harms associated with consumption of vitamin B supplements, although such harms would occur from vitamin B intake unlike that studied, so this gets a satisfactory grade. Two of the three studies referred to in the journal article are detailed; a brief reference is given for the third. In addition to the discussion of the studies, a quote was pulled from an editorial in the journal that published the studies. No other treatment options for lowering risk of heart attacks or strokes are mentioned. It’s clear from the story that B vitamins have been in use for some time by many people for these purposes. It’s clear from the story that B vitamins have been in use for some time by many people for these purposes. We can’t be sure if the story relied solely or largely on a news release.

Output: Study: Heart attacks not cut by B vitamins


Input: Consider Input: "The Road We’ve Traveled -- a 17-minute film from President Barack Obama’s re-election campaign -- touts his achievements in health care, saying that the Affordable Care Act has substantially expanded coverage for millions of Americans. We’re checking several claims from the film, including one that ""2.5 million young adults now have coverage."" The law requires insurers to provide dependent coverage for children up to age 26 on all policies. The goal is to prevent young adults from becoming uninsured when their parental or college plans would otherwise run out. This provision took effect in September 2010. We found support for the film’s statistic in a Health and Human Services analysis of data from the National Health Interview Survey, a longstanding survey conducted by the federal Centers for Disease Control and Prevention. The survey found an 8.3 percentage point increase in insurance coverage for the 19-to-25 age group between the third quarter of 2010 and the second quarter of 2011 -- from 64.4 percent to 72.7 percent. The analysis then multiplied 8.3 percent by 29.7 million -- the number of people nationally in that age group -- to come up with the number 2.5 million. We’ll note that the original CDC study, using slightly different methodology, found a smaller number. Using annual and semi-annual figures rather than quarterly numbers, the number grew by 1.3 million. The HHS analysis makes the case that, for various technical reasons, its method is superior. We think both estimates are reasonable, and while the 2.5 million figure got more traction in the media, we also think it’s worth noting that the underlying federal study offers an alternative -- and smaller -- number. In essence, the film cherry-picks the higher number. So the statement is accurate but needs clarification, which fits our definition of ."


Output: "Because of the new health care law, ""2.5 million young adults now have coverage."
