Summary of effect of sensitivity analyses on associations between key indices and stunting risk. (a) Original regression model (online Supplementary Table S5; N = 3791); (b) model with maternal age included (N = 3337); (c) model with maternal education included (N = 3625); (d) model with paternal height included (N = 2723); (e) model with orthogonal variables included (N = 3434). RR, risk ratio; 95% CI, 95% confidence interval (error bars); BMI, body mass index. Stunting and BMI-for-age were defined using the Centers for Disease Control and Prevention 2000 reference. Flush toilet includes that connected with septic tank or sewerage system; unprotected drinking water sources: unprotected dug well, or water taken directly from pond or stream; protected sources: public standpipe, protected dug well or spring, or water from bottles or tanker truck.
