BMD T-scores (mean and SE) at different skeletal sites for native Chinese women, by quartiles of bone turnover markers. Abbreviations: BAP-bone-specific alkaline phosphatase, OC-osteocalcin, sCTX-serum cross-linked C-terminal telopeptides of type I collagen (CTX), sNTX-serum cross-linked N-terminal telopeptides of type I collagen, uCTX-urinary CTX, uNTX-urinary NTX, uDPD-urinary deoxypyridinoline, PA-posteroanterior spine, FN-femoral neck, Q1-first quartile, Q2-second quartile, Q3-third quartile, Q4-fourth quartile. *P = 0.045–0.000 compared with Q2, Q3 and Q4. ▲ P = 0.029–0.000 compared with Q3 and Q4. # P = 0.013–0.000 compared with Q4.
