Given a paragraph and a claim, classify it this way: If the claim contradicts the evidence present in the paragraph, classify the claim as '0'. If the claim has multiple supporting *AND* contradicting evidences, classify the claim as '1'. If the claim has supporting evidence and the paragraph is in overall favor of the claim, then classify the claim as '2'.
Example: Paragraph: While the financial costs of screening mammography&!1-positive recalls&biopsies were not included in the study,readers would benefit from being reminded that recall mammography&biopsies increase patient financial costs.This article leads with valuable information for all women over age 40 by stating "Getting screening mammograms every two years instead of annually reduces the chance of a!1 alarm,a new study shows." Unfortunately the writer doesn't quantify or elaborate adequately on that reduction.Instead,the writer later focuses on how women undergoing screening mammography shouldn't be anxious if they experience a recall because over half of women who have screening mammograms for 10 years will be recalled.Readers would have been better served if the writer had emphasized the significant reduction in both recall mammograms&!1-positive biopsies in women who are screened every two years rather than annually.Part of the continuing controversy over screening mammography focuses on annual versus biennial screening.Because this study showed a significant reduction in the percentage of those recalled&needing biopsies among women who are screened every other year,with no statistically significant increase in late-stage diagnosis of breast cancer,the article should have emphasized those important findings.The piece states that the researchers noted that "!1 positive recalls may cause inconvenience&anxiety and biopsies can cause pain and scarring." This article fails to include several important facts about the study.1)This is a prospective cohort study of women screened between 1994-2006.2)Most of the mammograms were film rather than digital.3)Few women underwent screening for the entire 10 year period.4)Screening mammography recall rates are influenced by the skill of the radiologists who read the mammograms.There was no disease mongering.No independent experts were quoted.The story did an adequate job comparing at a very high level annual screening versus biennial screening.Screening mammography is widely available throughout the United States.The study did not examine a new procedure.There's no evidence that the story relied solely on a news release.
Claim: Annual Mammograms May Have More False-Positives
Example solution: 1
Example explanation: This article reports on the results of a study of nearly 170,0 women who had screening mammograms beginning between age 40-59.The study found that over ten years of screening mammograms,over half of the women will experience a!1-positive recall for additional mammography.In addition,7%-9%of the women will have a biopsy for a suspicious lump which is not cancerous.Both of those percentages decrease if the woman is screened every other year rather than every year.Even with biennial mammography,41%of women will experience a recall over 10 years of mammography.The study's Principal Investigator emphasized that "in most cases,a recall doesn't mean you have cancer." She hoped this knowledge would reduce the anxiety of women who are recalled.The story never explained the size of the decrease in the number of!1 positives between annual(61.3%) and biennial screening(41.6%).Our first two reviewers were a researcher who specializes in health decisions and a breast cancer survivor trained in evidence by the Natiional Breast Cancer Coalition's Project LEAD.This study is valuable because it helps to quantify and compare the harms of annual and biennial screening,specifically the number of!1 positives and the number of unnecessary biopsies.Prior to this study,estimates of!1 positive screening mammography rates varied widely.The critical question is whether you can do less frequent screening,subject women to fewer harms and get similar results in terms of detection of "early stage" cancer.This study's data seems to suggest that answer is yes.

Problem: Paragraph: Discussion of costs is relatively unimportant as most individuals would know how much beer costs. The story did quantify the benefits of one parameter by quoting the abstract "incidence of upper respiratory tract infections was 3.25-fold lower" but it was not mentioned that these were self-reported upper respiratory tract infections. The story mentions that there was 'significantly less evidence of inflammation.and lower counts of white blood cells than the placebo group" but does not provide numbers. The story also states that the 'beer experiment' showed benefits of minimizing post-race damage. But the study didn't measure damage, it measured blood markers of immune function. In the study, participants consumed 1-1.5 liters/day of non-alcoholic beer (or a placebo) for 5 weeks total. There could be several potential adverse effects such as weight gain from extra calorie consumption, imbalances in nutrients if the liquid replaced other fluids, etc. No potential harms were mentioned. The quality of evidence in the research study was low as it was a non-peer reviewed abstract that was presented at a scientific meeting only, and this is not mentioned. While the treatment (non-alcoholic beer) was compared to a placebo in a double-blinded design, the nature of the placebo is not known, other than that it was a beverage. The research does not mention whether numerous important factors were controlled in the study design (the training regimens of the participants, their diets, their total beverage consumption, etc) and these extensive limitations are not mentioned in the story. No disease mongering. Marathon running was described as "punishing to the body, causing muscle soreness and inflammation." This is accurate. The story quotes the lead author extensively. Unfortunately, no other independent perspectives are provided. No potential conflicts of interest are noted. The article does not mention potential alternatives that might aid marathon recovery, including any other dietary alterations, and does not discuss the advantages and disadvantages compared with any other approaches. Not applicable. The availability of nonalcoholic beer is not in question. However, it is not clear from the original abstract whether the type of beer matters, as the brand and/or the characteristics (such as calories) were not provided. This is not mentioned in the story. (note: the brand was provided in a press release) The treatment, beer, is not novel, and is not presented as such. Other substances that also contain the purported active ingredient, polyphenols, are discussed. There was an American College of Sports Medicine news release for the abstract, but it doesn't appear to have been relied upon. Maybe it should have been, since the news release actually includes a disclaimer the story did not include that the research was presented at a professional meeting but has not been peer-reviewed.
