| Minimally adjusted model | 512 | 14.3 (12.5; 16.4) | 13.3 (11.6; 15.3) | 16.1 (14.0; 18.4) | 13.6 (11.8; 15.6) | 0.231 |

1 Estimates are means (95% CI). ANCOVA regression models were used to examine the difference in mean HCC at endline and the magnitude of change in HCC. Minimally adjusted: adjusted for baseline value of HCC, age, and district. Fully adjusted: Minimally adjusted + sex, LAZ, WAZ, wasting, health center and maternal marital status. HCC: Hair cortisol concentrations; MNP: micronutrient powder; PZ: preventive zinc; TZ: therapeutic zinc. 2 Results shown as geometric mean (95% CI) (HCC were log-transformed and then the estimates were back transformed using excel’s exponential function). 3 Results shown as arithmetic mean (95% CI) and change is from baseline to endline.
