a
P value represents the comparison between all groups;
b
there is no difference between phototherapy and jaundiced control groups (t-test). Newborns in the phototherapy group were sampled for the study 24 hours after phototherapy. TSB, total serum bilirubin (mg/dl); SD, standard deviation;
*
Chi-square test;
**
Kruskal-Wallis test
