@normahorn McCormick is a chiropractor so is "patients" appropriate?

@baguette this kind of detail in evaluating DEXA's was valuable for you. For some of us, the error rate isn't as important as the overall picture. In other words, for scores below, say, -3.5, I don't think error matters. I have been told that changes plus or minus -.5 are clinically significant, and my report also says not to use the femur neck score to evaluate changes. I have kept a chart of my DEXA's since 2001 and I look at trends rather than specific values. For me, considering issues with DEXA accuracy did not argue against meds!
