Area under the ROC curve (AUC) and 95% confidence intervals (CI) are given for each GRS in separate unadjusted models. N = number of participants. N cases = number of fracture cases.
Abbreviations: eBMDGRS, genetic risk score for estimated bone mineral density of the heel; FN-BMDGRS, genetic risk score for bone mineral density in femur neck; LS-BMDGRS, genetic risk score for bone mineral density in lumbar spine.
*For vertebral fractures, only N = 1475 participants were included.
