INS and Hypoglycemia: There were no statistically significant differences in glyburide vs insulin initiation in risk for neonatal hypoglycemia (0.85 [95% CI, −1.17 to 2.86] per 100 births), jaundice (0.02 [95% CI, −1.46 to 1.51] per 100 births), shoulder dystocia (−1.05 [95% CI, −2.71 to 0.62] per 100 births), or large-for–gestational age categories (−2.75 [95% CI, −6.31 to 0.80] per 100 births).
