Heat map of robustness checks. Robustness checks of weight meta-analyses for children younger than five. Effect-size estimates for all of the 32 main meta-analyses are shown along the top row, with estimates from leave-one-out analyses are below. Effect size is indicated by color warmth (warmer colors are larger effect sizes) with P-values written diagonally on each estimate. P-values below 0.05 are shown in red. Heterogeneity, as indicated by I ², is plotted from each of the 32 meta-analyses to the right of the heat map. Effect sizes became significant in 8 out of 450 estimates. Heterogeneity is above 80% in all robustness checks, except when Awasthi 2008 is dropped, in which case it is below 80% for all 32 models
