Plasma calcium and PTH concentrations. (A) Plasma calcium concentrations (mg/dL) were significantly (1P < 0.05 vs. Bsl, Pre, 1-h, 24-h, 48-h, 72-h, and 168-h) increased at Post. (B) Plasma PTH concentrations (pg/mL) were significantly (2P < 0.05 vs. Pre, Post, 72-h, and 168-h) decreased at 1-h. Figure legend provided in ‘A’. Data presented as mean (SD).
