Associations of fetal and childhood weight with kidney outcomes at the age of 6 years (n=6482). Effect estimates (95% CI) represent regression coefficients based on multiple regression models and reflect the difference per 1 SD increase in standardized residual score for (estimated) weight measures at different time points (details on conditional regression models are in Supplemental Material). Models are adjusted for maternal age, body mass index, parity, ethnicity, educational level, folic acid supplementation, and smoking during pregnancy as well as child sex, breastfeeding, current age, and body surface area. Results for models additionally adjusted for kidney volume are given in Supplemental Figure 3. SDS, SD score.
