Teacher: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'.
Teacher: Now, understand the problem? Solve this instance: Paragraph: The story attempted to discuss cost by citing the difference in pricebetween shoulder surgery ($13,000) and the PRP treatment ($1,000, in this case for two injections). This is sufficient enough for a Satisfactory rating, but barely. While this does give readers some idea of the possible cost difference in treatments, there is no assurance that the charges in the author's case are typical for those for the generalpublic. It is simply one single data point which is fairly useless to the public. And, since there is no evidence of benefit or how many shots one might require, cost could be all over the place. The story gives no information on quantified benefits measured in PRP research, and instead focuses only on the author's experience. The only mention of potential harms in the story comes in this statement: "The American Academy of Orthopedic Surgeons which says PRP 'holds great promise' describes the risk as minimal." That's notacceptable given that there is no explanation of what those risks might be. Readers areleftclueless when it comes to questions of potential harms. Simply put, the discussion on the quality of evidence here is at best minimal, just the experience of one patient who happens to be a writer for the Washington Post. The story does cite a "recent pilot study" from a Canadian clinic of just seven rotator cuff injury patients who underwent PRP therapy. It said the study "showed tissue healing in five of seven patients . . . as well as improvements in their pain and function." But the story offers no information on how much healing or what degree of pain reduction or function, information readers need to consider a new therapeutic approach. There is no discussion of the growing body of evidence that has yet to show PRP actually improves clinical results. High-quality research, including a Cochrane systematic review, shows no benefit from injecting PRP. As Cochrane's review noted: "The quality of the evidence is very low, partly because most trials used flawed methods that mean their results may not be reliable.In terms of individual conditions, we were able to pool results from six studies and found no differences in long-term function betweenthose who received PRT during rotator cuff surgery and those who did not." When it comes to shoulder injuries like rotator cuff tears, the story does not disease monger. However, the author's claim that a vaccination injection resulted in the shoulder tear was an unusual claim, and one that we're dubious of. Along with quotes fromthe author's physician (whohas already posted the storyon his website)there are quotes froma researcher who was involved in one small clinical trial on PRP. The inclusion of the researcher just barely squeaks by as sufficient to earn a Satisfactory rating here. However, the story would have been much stronger had the author interviewed an expert who disagrees with these two sources, which wouldn't be hard to find given the Cochrane review and other systematic reviews that cast a less rosy glow on PRP. The story is basically touting a possible new therapy as an alternative to traditional rotator cuff surgery, but it does a poor job of comparing them in an evidence-based manner. The story explains that platelets are removed from a patient's blood using a centrifuge, equipment readily available in most practices. It makes the point of advising readers to seek out practitioners who do the procedure frequently. The story suggests that the PRP procedure is becoming more available. The story does not make it clear thatPRP is not a new treatment, and that has been studied for many years now, including in rotator cuff tears. This story does not rely on a news release.
