In the first sensitivity analysis, which excluded the cases treated with insulin (Supplementary Table S3; n = 72), and in the second sensitivity analysis, which excluded the participants with diabetes in pregnancy (possibly undiagnosed pre-existing diabetes defined by fasting glucose ≥7.0 and/or 2 h glucose ≥11.1 mmol/L in a mid-gestation 75 g OGTT; Supplementary Table S4; n = 72), the list of lipid species most associated with the standardized birthweight percentiles, and the magnitudes of effect, were very similar to the list obtained in the main analyses of the complete set of subjects. Here, INS is linked to diabetes mellitus.
