Q: 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'.
Paragraph: Cost is particularly important when many patients may have to pay out of pocket for weight loss drugs. Thestory doesnot provide any information about thecost of orlistat, thecost of the foodin thestudy diets, or the cost of the counseling provided to study participants. A quotation from one of the study researchers suggeststhata low-carb diet might be acheaper alternative to a low-fat diet plus medication. While this is certainlypossible, it also seems possible that low-carb eating,with its emphasis on protein frommeat,would be more expensive than low-fat eating, and that this would cancel out any savings on medication. In any case,making any kind of judgment in this area would requiremore hard data, butthe story provides only speculation. The story earns points for noting the absolute reduction in blood pressure in each group. We wish, though, that it had provided the weight loss in similar terms of actualpounds or kilograms lost instead of as a percentage of bodyweight. Similar to the HealthDay piece, the story provides no information about the potential adverse effects of orlistat or a low-carbohydrate diet. Similar to the HealthDay piece,the story gives a decent overview ofthe basic study design and outcomes. However more information would have helped us judgehow well these diet plans might work in the real world. There isno information on who dropped out of the study or how well the two groups were able to adhere to the diet. In addition, the story states that low-carb dieters were advised to consume 20 g of carbohydrate per day, but itseems very unlikely that participants were able to maintain that level of carbohydrate restriction for almost a year. Overall, this story squeaks by with a satisfactory. The story does not exaggerate the prevalence or consequences of obesity. The story's only quotes come from Dr. Yancy, a researcher affiliated with the study. The story also does not informreaders that Dr. Yancy and another co-author on the study have received funding from the Robert C. Atkins Foundation, which promotesresearch on low-carb diets. Given the story's focus on blood pressure, itshould have mentioned how the results of this study might compare to treatment with blood pressure medication. Thestory mentioned thatorlistat, the weight loss medication tested in the study,is the active ingredient in Xenical andAlli. Unlike the competing piece in HealthDay, however, it did not specify that Xenical is a prescription drug and that Alli is available over the counter. Although this information would have been helpful, providing the trade names for both drugs is probably enough to orient most readers. The story mentions that both low-carb and low-fat diets are proven to produce weight loss. However, it suggests that we should be surprised that a low-carbohydrate diet could produce such beneficial effects on blood pressure. In fact, this effect was well-documented in another comparisonof weight loss dietspublished in JAMA in 2007. The story lifts two quotes directly from a news release put out by Duke University. While the story admits thatthe quotescame froma release,it doesn'tperformthe basic task of finding another source to provide an alternateviewpoint. The reader is left wondering if this is journalism or simply an extension of the Duke University press office. Claim: Low-Carb Diet Lowers Blood Pressure
