Kaplan–Meier survival curves. (a) Overall, the IPPFE group had significantly worse survival than the IPF group (log rank , generalized Wilcoxon ). (b) In the GAP stage I, there was no significant difference between the IPPFE and IPF groups in terms of survival. (c) In the GAP stages II + III, the IPPFE group had significantly worse survival than the IPF group (log rank , the generalized Wilcoxon ).
