Alterations in the abundances of gut microbial genera in CCP. (a), Six genera whose abundances had the greatest reductions in CCP patients relative to HCs, with comparisons by a two-tailed Wilcoxon signed-rank test (sum of the mean <2.3, difference of the mean >2.5, see Table 2, Supplementary Digital Content 1, http://links.lww.com/CTG/A229). *P < 0.05, **P < 0.01, ***P < 0.001, and ****P < 0.0001. (b), The AUROC curve analysis of the performance of 6 genera in the diagnosis of CCP. Faecalibacterium: AUC = 0.80 (0.68–0.80, P < 0.001), Subdoligranulum: AUC = 0.65 (0.52–0.65, P < 0.05), Phascolarctobacterium: AUC = 0.71 (0.59–0.71, P < 0.01), Bifidobacterium: AUC = 0.65 (0.51–0.65, P = 0.07), Collinsella: AUC = 0.67 (0.54–0.67, P < 0.67) Eubacterium: AUC = 0.70 (0.56–0.70, P < 0.01). The use of each of the 6 individual arcsine square root transformed abundance values, together with the coefficients from multivariate logistic regression: AUC = 0.92 (0.84–0.92, P < 0.001). AUC, area under curve; CCP, children with chronic pancreatitis; HC, healthy control.
