Trabecular bone score
Trabecular bone score values of the same lumbar vertebrae were calculated based on DXA images using software (TBS iNsight, version 2.1.2.0, Medimaps, Mérignac, France). The software takes the anteroposterior spine raw image(s) from the densitometer (Hologic Corp, Bedford, MA, USA), including the BMD region of interest; therefore, the TBS calculation was conducted over the same region of interest as the BMD measurement. The reproducibility of TBS assessments in several mono-center studies was reported between 1.1% and 1.9% CV [
