Abbreviation: FDR, false discovery rate.
Lasso logistic regression (adjusted for maternal age, pre-pregnancy BMI, family history of diabetes, and maternal race) performed to identify sets of metabolites jointly associated with case-control status.
Fold change (GDM case/control).
Multivariable logistic regression model based on lasso-selected metabolites adjusting for maternal age, pre-pregnancy BMI, family history of diabetes, and maternal race.
Univariate logistic regression of each lasso-selected metabolite adjusted for maternal age, pre-pregnancy BMI, family history of diabetes, and maternal race.
