Odds ratios of low age-, sex-, and race-specific areal bone mineral density (aBMD) Z-score at each site per one-decile lower in (A) upper- and (B) lower-body muscle strength (Reference deciles using FitBack reference values). Binary logistic regression (low aBMD identified as Z-score less than ‒1.0, according to according to van Atteveld et al.⁴ and normal aBMD identified as Z-score higher than ‒1.0) was used to estimate odds ratios with 95% confidence intervals. Adjusted models included time from treatment completion (years), radiotherapy exposure (yes/no) and body mass index. Age-, sex-, and race-specific aBMD Z-score at each site is presented using international reference data from the Bone Mineral Density in Childhood Study.²⁷
