Table 2 Comparison of the means/medians of dietary calcium intake, total serum calcium level and ionized calcium levels in case and control groups
Variable | Cases (n = 42) | Controls (n = 42) | P |
|---|---|---|---|
Total serum calcium level (mmol/l), (mean ± SD) | 1.99 ± 0.35 | 2.19 ± 0.22 | 0.007 |
Ionized calcium level (mmol/l), (mean ± SD) | 1.1 ± 0.11 | 1.2 ± 0.13 | 0.000 |
Dietary calcium (gram/24 h), (median, IQR) | 704, 458–1183 | 1115,753–1878 | 0.049 |
