However, we found a relation between insulin dosages at delivery and HDP incidences for all women with T1DM (dosage ≥ 42 IU/L; AUC = 0.671, p = 0.0361), and among all women with T2DM without CH (dosage, ≥80 IU/L; AUC = 0.690, p = 0.0124), respectively. This evidence concerns the gene C4B and type 1 diabetes mellitus.
