| Unadjusted OR (95% CI) | P value | Adjusted OR (95% CI) | P value | |
| Total calcium (<8 mg/dL) | 4.3 (3.0 to 6.1) | <0.01 | 2.5 (1.6 to 3.9) | <0.01 |
| Corrected calcium (<8 mg/dL) | 3.1 (2.2 to 4.4) | <0.01 | 1.7 (1.1 to 2.6) | 0.02 |
| Hospitalization | 1.4 (1.0 to 1.9) | 0.07 | 1.0 (0.7 to 1.6) | 0.96 |
