Significance of household environment and survey factors in gut microbiome diversity. The significance of the factors tested amongst the α diversity indices of Shannon index and Pielou’s evenness in children and infants. Significance was assessed via p value, with values differentiated by color. Significant values (p < 0.05) are shown with the darkest red. The direction of the trend is identified in the factor label (y-axis). For correlation tests of continuous variables, the direction of the significant association is indicated with a + or -. For categorical data, the group with significantly greater diversity is underlined
