Correlations among the GM strains, fecal SCFAs, and the UN clinical indicators. a Contributions of SCFAs, Weight to age, and GM on the physiological indicators of UN. The thicker lines represent the higher contributions of variables on the physiological indicators. The oranges, green, and grey lines represent the adjusted P-value < 0.01, 0.01-0.05, and \(\ge 0.05\), respectively. The blue and red boxes represent the positive and negative correlations among the clinical indicators, respectively. b Corre-lation heatmap between the SCFAs and GM strains. c Correlation heatmap between the SCFAs and the physiological indicators of UN. d Correlation heatmap between GM strains and the physiological indicators of UN. The blue and red boxes represent the positive and negative correlations, respectively. *, Padj < 0.05; **, Padj < 0.01; ***, Padj < 0.001
