Text: Mean (SD) total serum bilirubin levels in zinc and placebo groups were 13. 9 (2. 5) vs. 13. 4 (1. 9) mg/dL (mean difference 0. 566 ; 95 % CI -0. 535, 1. 668, P = 0. 038) at 48 h, 13. 1 (2. 7) vs. 12. 8 (2. 3) mg/dL (mean difference 0. 234 ; 95 % CI -1. 011, 1. 479, P = 0. 708) at 96 h and 8. 0 (2. 0) vs. 8. 6 (1. 2) mg/dL (mean difference -0. 569, 95 % CI -1. 382, 0. 242, P = 0. 166) at 144 h. Although the mean duration of phototherapy in the zinc group was less by 21. 3 h (95 % CI 11. 6, 30. 9, P = 0. 052), the difference was not significant.
