^*Plus–minus values are means ± SD.

^†The composite perinatal outcome included stillbirth, neonatal death, hypoglycemia, hyperbilirubinemia, elevated cord-blood C-peptide level, and birth trauma.

^‡The results of some blood tests were not available either because samples were not obtained or were not obtained according to protocol or because they could not be assayed owing to a laboratory processing error.

^§Data were not available in some cases because some women delivered at outside institutions.
