Results expressed as exponentiated coefficients which indicate the fold change in COP cells with each increase in unit of the comparison variable.

ALM = appendicular lean mass; BMD = bone mineral density; BMI = body mass index; CI = confidence interval; COP = circulating osteoprogenitor.

^*Values are significant.
