Estimation of importance of the urinary VOCs using Random forests analysis. (A) The top eight VOCs with Gini coefficients by RF. (B) Comparisons of peak height of volatile organic compounds in patients with EC and HC. The peak height of Cyclohexanone-D (A), 2,3-Butandiol (B), Methyl decanoate (C), (E)-Ethyl-2-hexenoate (D), 2-Acetylfuran (E), 2-Methyl-butanoic acid methyl ester (F), 2-Isopropyl-3-methoxy pyrazine (G), Dimethyl trisulfide (H). *P < 0.05, **P < 0.01, ***P < 0.001 (Mann–Whitney U-test). The error bars in scatter plots represent the median and interquartile range.
