BMD, bone mineral density; FN, Femoral neck; TBS, trabecular bone score.
aLowest: participants with a lowest T score of ≤ − 2.5 at any of the three sites (spine, FN, or total hip).
bCombined lowest (BMD and TBS): participants with a lowest T score of ≤ − 2.5 at any bone site and or a spine TBS of ≤1.230.
