Trabecular bone parameters of the 5th vertebral body: the four trabecular bone microarchitecture parameter (BV/TV, TbN, TbTh, TbSp) measured by micro-CT and the grayscale measured by dental CT.

SD = standard deviation; CV = coefficient of variation (100×SD/mean); BV/TV = percent bone volume [bone volume (BV)/total volume (TV)]; TbTh = trabecular thickness; TbSp = trabecular separation; TbN = trabecular number; vCanGrayscale = volumetric cancellous bone grayscale value.Trabecular bone parameters of the 5th vertebral body: the four trabecular bone microarchitecture parameter (BV/TV, TbN, TbTh, TbSp) measured by micro-CT and the grayscale measured by dental CT.SD=标准差（standard deviation）；CV=变异系数（coefficient of variation，即100×SD/均值）；BV/TV=骨体积分数[骨体积（bone volume, BV）/总体积（total volume, TV）]；TbTh=骨小梁厚度（trabecular thickness）；TbSp=骨小梁分离度（trabecular separation）；TbN=骨小梁数量（trabecular number）；vCanGrayscale=松质骨体积灰度值（volumetric cancellous bone grayscale value）。第五椎体的骨小梁参数包括：经显微CT（micro-CT）测得的4项骨小梁微结构参数（BV/TV、TbN、TbTh、TbSp），以及经牙科CT（dental CT）测得的灰度值。
