strengths and weaknesses that warrant discussion. The use of clinical measurements of total body fat using dual energy x-ray absorptiometry and abdominal fat using magnetic resonance imaging, as well as clinical laboratory measurements of other risk factors, is a marked strength of the study. Another key
