Fig. 7. Histological inflammation of intestine improves the liver transplantation-free survival in PSC patients.
a Diagram of the study design for the PSC cohort. b Kaplan–Meier survival curves of PSC patients according to the presence of histological inflammation of intestine. (Histological inflammation: n = 49; No histological inflammation: n = 21; 4 patients with histological inflammation and 1 patient without were excluded to avoid bias caused by patients already being listed for a liver transplantation since they reached endpoint within 3 months from inclusion). Survival probabilites for each group are shown using the Kaplan-Meier estimator with corresponding (coloured) 95% confidence intervals and the log-rank test (P = 0.028). Average survival times are shown in figure using restricted mean survival time (RMST). Source data are provided as a Source Data file.
