Table 1 Relative genus abundance associations with future HAZ estimated using multivariable between-within twin regression models for genera with a significant difference in degree centrality between cases and controls

Coefficients are expressed as the average difference in future HAZ per 0.1 % difference in abundance between siblings
90 % CI 90 % confidence interval, HAZ height-for-age z-score
^aMedian difference in relative abundance between siblings in a twin pair
^bModels could not be fit in the Malawi cohort because these genera were only identified in ≤2 samples
