Results are from multivariate linear regression models. Coefficients represent mean differences (95% CIs). All hypotheses were tested with t tests. Adjusted models include all control variables displayed in Table 1 as well as interaction terms of baseline stunted growth and age <12 mo with all covariates. *Significance at the 5% level. **Significance at the 1% level. #Significance at the 10% level. CBGM+NS, community-based growth monitoring including nutritional supplementation; HAZ, height-for-age z score; HBGM, home-based growth monitoring; Ref., reference category; WAZ, weight-for-age z score.
