Delivery outcomes were also improved in the insulin treatment group compared with the control group, including lower neonatal weight (Z = −2.200, P = 0.028), incidence of macrosomia (χ2 = 4.092, P = 0.043), gestational age (Z = −3.427, P = 0.001), and rate of intensive care unit (ICU) conversion (P = 0.014). This evidence concerns the gene INS and Large for gestational age.
