  1. Results are derived from multivariate multi-level linear regression models, with “survey” as random effect. The regression coefficients represent the absolute % increase in the dependent variables (WHZ−2, MUAC125, MUAC125) between the 2 categories of the independent variables (long legs, stunted, sex, age). All models were adjusted for all covariates
