Given the task definition, example input & output, solve the new input case.
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
Output: 1
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.

New input case for you: Paragraph: There was no discussion of costs. Were people to begin taking B vitamins in the quantities necessary to show improvement along the lines of what has been seen in some of the studies mentioned, B vitamins could become a lifelong treatment with significant cumulative costs. The slant of the story was to question the wisdom in augmenting vitamin B intake in light of the studies failing to demonstrate benefit. The story itself, however, reported on several pieces of evidence over time rather than reporting on the results of a specific study or studies. Where it did provide numbers on benefits, it did so in a clear and cautious way. For example, it noted "a recent study in which brain atrophy (or shrinkage, which occurs in older people who are losing brain function) slowed by 30% in elderly patients with both high homocysteine levels and mild cognitive impairment who took a B vitamin pill daily for two years. Brain shrinkage occurred at a rate of about 0.75% in the people taking B vitamins in the study, compared with a rate of 1.1% per year in a group that took a placebo." By including the actual percentages for people in both groups, the story shows the reader that the shrinkage was not dramatic to begin with and that the difference between the two groups could also be described as a 0.26 percentage point difference. The story did include information about possible side effects and harms associated with excessive consumption of B vitamins. The story provided a reasonable description of several studies in which outcomes were not changed with vitamin B supplementation. There was a useful quote by one of the researches indicating that only a minority of studies showed any indication of benefit from increasing vitamin B intake. We wish it had taken a little more care in making clear distinctions between the different populations being studied. In some cases, the studies were focused on anyone of advanced age, while in others they were focused specifically on Alzheimer's patients, but there was no discussion in the story about whether these differences may also have accounted for the different findings among the studies. The story did not engage in disease mongering. The story detailed several studies of the relation between the B vitamins and cognitive impairment; it included quotes from two researchers (Haan and Miller) in the field who are at different institutions but have several studies that they have worked on and published together. There was no discussion of how the fortification of common foods in the supply chain, such as grains, flour, cereal, energy bars and drinks, has affected the levels of B vitamin. There was also no mention of other specific therapies to stop cognitive decline. The story described the urge to rush out and purchase B vitamins, which is suggestive of their ready availability. The story neglected to mention that many foods are already fortified with B vitamins, which may already cover the recommended intake levels for many readers. This story provided a nice overview of what is known about B vitamins in relation to age- and disease- related cognitive decline. The story does not appear to rely solely on a news release. It is not clear why this information about the long-term research interest of two local scientists is news right now, but it is an interesting piece nonetheless.
