Note: Magnitude of fracture odds associated with each SD, LSC, or SEE increase (+) or decrease (−) in radius bone variables obtained from pMRI was determined using a binary logistic regression model. Models were examined with and without adjusting for age. CI = 95% CI (lower, upper).

Abbr: BV/TV, bone volume/total volume; CI, confidence interval; LSC, least significant change; MI, Model-Independent; OR, odds ratio; pMRI, peripheral magnetic resonance imaging; SD, standard deviation; SEE, standard error of the estimate; Tb.N, trabecular number; Tb.Sp, trabecular spacing; Tb.Th, trabecular thickness.
