a
p value obtained from comparison of the groups who received phototherapy, Kruskal-Wallis test;
b
p value obtained from comparison of all groups, Kruskal-Wallis test;
SCE1: Sibling Chromatid Exchange frequency, before phototherapy; SCE2: Sibling Chromatid Exchange frequency, after phototherapy; T0Bil: bilirubin value at the time of hospitalization; T24Bil: total bilirubin value 24 hours after hospitalization; TR6 Bil: bilirubin value 6 hours after discontinuation of phototherapy; ΔBil: Hourly bilirubin reduction rate
