Table 3 summarizes the neonatal cytopenia outcomes with their CBC results. There were no differences between the groups regarding occurrence of anemia, leukopenia, or thrombocytopenia. The median Hb for the three groups were 177g/L (IQR 38g/L) for the IBD thiopurine group, 180.5g/L (IQR 40g/L) for the IBD non-thiopurine group, and 181g/L (IQR 37g/L) for the control group. There were 11 cases of mild neonatal anemia (10%), 1 in the IBD thiopurine, 5 in the IBD non-thiopurine, and 5 in the control group (P = .725, Table 3). The gene discussed is GSTM1; the disease is anemia.
