Q: Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.
Question: Is progressive increase in body mass index associated with a progressive increase in joint space narrowing in obese women with osteoarthritis of the knee?
Answer: In obese patients with OA, progressively higher BMI values were not accompanied by a progressively increasing rate of JSN. Joint loading was not evaluated, but it is possible that marked obesity limited the functional capacity of some subjects with OA, protecting their knees from loading. For investigators considering eligibility criteria for a trial of a structure-modifying OA drug, these data suggest that recruitment of patients with a BMI much higher than 30 kg/m(2) will not enrich the sample of subjects who will have more rapid JSN than those with a BMI of only 30 kg/m(2).
A:
no
