Table 2: Demographic and biochemical characteristics of patients that develop hypocalcemia following thyroidectomy.
| Normocalcemia (n = 76) | Hypocalcemia (n = 22) | P | |
| Age | 62.9 ± 1.6 | 44.4 ± 3.4 | < 0.0001 |
| BMI (kg/m2) | 29.2 ± 0.6 | 24.9 ± 0.9 | 0.0045 |
| iPTH ( pg/ml) | 61.7 ± 6.2 | 15.5 ± 2.4 | 0.0014 |
| Preoperative calcium (mg/dl) | 9.51 ± 0.10 | 9.29 ± 0.15 | 0.28 |
| Postoperative calcium (mg/dl) | 8.42 ± 0.05 | 7.42 ± 0.06 | < 0.0001 |
| Change in calcium (mg/dl) | -1.05 ± 0.12 | -1.94 ± 0.12 | 0.003 |
| Albumin (g/dl) | 3.57 ± 0.03 | 3.55 ± 0.07 | 0.96 |
Shown are the number of observations (n), mean values ± SEM, and the P values. Student t test was employed to probe for differences between groups. BMI: Body Mass Index; iPTH: Intraoperative PTH Levels.
