Previous Birth Size and Current Glucose Tolerance Jointly Distinguish Fetal-Growth Risk in a Subsequent Pregnancy: Aggregate source data and display-reproduction code

This deposit contains aggregate source data and display-reproduction code for the manuscript "Previous Birth Size and Current Glucose Tolerance Jointly Distinguish Fetal-Growth Risk in a Subsequent Pregnancy: A Longitudinal Cohort Study" (BJOG submission candidate). The repository includes aggregate source data underlying Table 1, Figures 1-3, Figure S1 and Supporting Information Tables S1-S10D, together with R code to reproduce the principal graphical displays from these aggregate data. The final longitudinal cohort comprised 6,654 women; the primary adjusted 3x3 model used N=6,652. The package contains no patient-level records, direct identifiers, linkage keys, free text or exact individual dates. The primary 3x3 models are additive logistic main-effects models (no interaction term); results should not be interpreted as effect modification. This deposit is not a prediction model, screening algorithm or clinical management rule. Individual-level clinical data remain subject to institutional data-governance requirements and are not distributed here.
