Therefore, to determine if there were significant differences between the intervention and control groups that might impact the results, the baseline characteristics of the newborns were compared using Student’s t-test for the HCT and RBC, while the Mann–Whitney U test was performed for the GA, BW, APGAR scores, and day-1 Hb, aPTT, PT, LDH, and serum EPO levels and the one-sample binomial and χ2 tests were used to examine the nominal variables, namely sex and congenital anemia. This evidence concerns the gene GSTM1 and congenital anemia.
