Fig 5. Least squares estimates for WHZ scores by age-restricted sub-samples: Household wealth, health facility access, parental education, household sanitation and water variables.

Notes: The figure reports coefficients and 95% confidence intervals based on cluster-adjusted standard errors from multivariable least squares regressions of HAZ against all the variables listed in Table 1, as well as country-year fixed effects and dummy variables for every month of child age. Samples sizes for the regressions estimated for the various age groups are 67,384 (0–5 months; m0to5), 75,965 (6–11 months; m6to11), 76,711 (12–17 months; m12to17), 68,694 (18–23 months; m18to23), 129,174 (24–35 months; m24-35), 138,342 (36–47 months; m36to47), 132,242 (48–59 months; m48to59).
