Table 4. Comparison of Vitamin D Levels between Groups.
| Variable | Vitamin D (ng/mL) | p-value | ||
|---|---|---|---|---|
| Group I | Group II | Group III | ||
| Preop | 48.3 ± 11.6 | 21.5 ± 7.7 | 20.2 ± 6.6 | < 0.001 |
| POD 3 | 40.4 ± 10.7 | 31.2 ± 24.9 | 69.9 ± 16.4 | < 0.001 |
| POD 14 | 38.9 ± 8.9 | 38.9 ± 21.5 | 68.5 ± 17.9 | < 0.001 |
Values are presented as mean ± standard deviation.
Preop: preoperative, POD: postoperative day.
If p-value is significant, post-hoc Scheffe test will be applied. Significant difference: group I vs. II (p < 0.05) and group I vs. III (p < 0.05) at preop; group I vs. III (p < 0.05) and group II vs. III (p < 0.05) at POD 3; and group I vs. III (p < 0.05) and group II vs. III (p < 0.05) at POD 14.
