Average rate of apparent bone loss [change in areal bone mineral density (aBMD)], net bone loss [change in bone mineral content (BMC)] and of periosteal expansion (increase in bone width or area) as well as the simple correlation coefficients of these variables with age in 725 men aged 50–85 at baseline followed up prospectively for 90 months (the prospective MINOS study)
