All regressions control for village fixed effects. All regressions control for Age at the time of data collection, Mother is primary caregiver, Premature birth, Age of mother, Mother completed high school, Primary caregiver completed high school, Family asset, and Project treatment
Columns (1) and (4) use the full sample, columns (2) and (5) use the sample of females, and columns (3) and (6) use the sample of males. N is the total number of observations in each regression
Standard errors are in parentheses
The coefficient for “number of siblings = 4” is based on a small subgroup and is not statistically significant. It should be interpreted with caution due to potential sample limitations
* p value < 0.1 (marginally significant)
**p value < 0.05
***p value < 0.01
