Differences in serum periostin and traditional BTMs levels among the normal group, the osteopenia group and the osteoporosis group. (A) Serum periostin levels among three groups. (B–D) Serum bone formation markers, such as BALP (B), OC (C) and P1NP (D) among three groups. (E and F) Serum bone resorption markers, such as β-CTX (E) and TRACP 5b (F) among the three groups.
Notes: **P<0.01 vs normal group; #P<0.05, ##P<0.01 vs osteopenia group.
Abbreviations: BTMs, bone turnover markers; BALP, bone-specific alkaline phosphatase; OC, osteocalcin; P1NP, procollagen type 1 N-terminal propeptide; β-CTX, β cross-linked C-telopeptide of type Icollagen; TRACP 5b, tartrate-resistant acid phosphatase 5b.
