Although there was no significant difference of Hb between the A-LF and NA-HF groups at 3 months old (n = 44, Hb: 102.1 ± 1.3 mg/L vs. n = 19, Hb: 97.6 ± 2.7 g/L, p = 0.127), sFer of the A-LF group was lower than that of the NA-HF group (n = 44, sFer: 44.0 ± 2.8 mg/L vs. n = 19, sFer: 65.1 ± 2.8 mg/L, p < 0.05) (Table 2). The gene discussed is GSTM1; the disease is hydrops fetalis.
