---|---|---|---|---|---|
Group 1 | 28–50 nmol/liter | 0.362 ± 0.125 (54) | 0.319 ± 0.093 (15) | 0.347 ± 0.114 (25) | 0.444 ± 0.151 (12) |
Group 2 | 50–80 nmol/liter | 0.302 ± 0.092 (154) | 0.302 ± 0.090 (44) | 0.307 ± 0.092 (88) | 0.280 ± 0.097 (22) |
Group 3 | >80 nmol/liter | 0.315 ± 0.100 (233) | 0.299 ± 0.092 (125) | 0.349 ± 0.105 (84) | 0.279 ± 0.088 (24) |

All data shown are fractional Ca-ab (mean ± sd) with sample size given in parentheses. P value is for overall comparison. Subsequent group pairwise comparisons were performed after adjustment by Fisher’s least significant differences for multiple comparisons. Significant pairwise comparisons (P < 0.05) are noted as follows: all subjects: group 1 vs. group 2, P < 0.001, group 1 vs. group 3, P = 0.003; early pubertal: group 2 vs. group 3, P = 0.008; late pubertal: group 1 vs. group 2, P < 0.001, group 1 vs. group 3, P < 0.001.
