Functional analysis of the gut microbiota in healthy control and gestational diabetes mellitus groups. A Boxplot of differential functions between the control and gestational diabetes mellitus groups. The differential pathways were identified using Tax4Fun and LEfSe, *: P < 0.05, **: P < 0.01. LEfSe: linear discriminant analysis. B Heatmap of Spearman’s rank correlations between differential genera (LEfSe: P < 0.05 and linear discriminant analysis threshold value > 2) and differential pathways. Bars that tend toward red and tend toward blue represent positive and negative correlations, respectively
