  1. β: standardized regression coefficient, R2: adjusted R2.
  2. Independent variables included in each model are DXA-HSA indices (CSANN, CThNN, SMNN, BRNN, CSAIT, CThIT, SMIT, and BRIT) in model 1; DXA-HSA indices and total hip BMD, height, weight, and age in model 2; CT-HSA indices (CSANN, CThNN, SMNN, BRNN, CSAIT, CThIT, SMIT, and BRIT ) in model 3; CT-HSA indices, total hip BMD, height, weight, and age in model 4.
  3. CSA: bone cross-sectional area, SM: section modulus, CTh: average cortical thickness, BR: buckling ratio, NN: narrow neck region, IT intertrochanteric region, FL: fracture load, SC: stance configuration, FC: fall configuration.
