^aBMD levels are expressed as the mean ± s.d.

^bThe ranges of SII quartiles 1–4 were <376.20, 376.20–514.90, 515.00–705.50, and >705.50 in premenopausal women and <337.80, 337.80–463.00, 463.10–644.00, and >644.00 in postmenopausal women, respectively.

^cP values were derived from Kruskal–Wallis tests among different SII quartile groups.
