Gradient-boosting models were trained to predict IT, basal insulin (BI), and prandial insulin (PI) requirements. Model discrimination was assessed using repeated stratified five-fold cross-validated area under the curve-receiver operating characteristic (AUC-ROC) (nested cross-validation). Feature importance and interpretability were evaluated with SHapley Additive exPlanations and permutation analyses. Differential microbial abundance was analyzed by ANCOM-BC2 (analysis of composition of microbiomes with bias correction, version 2), and metabolic pathways were predicted via PICRUSt2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Women requiring insulin were older and had higher pre-pregnancy body mass index (BMI), fasting plasma glucose, 1-hour oral glucose tolerance test glucose, and glycated hemoglobin than diet-treated women (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05 for all).
