Figure 2 The probability of remaining in inflammatory (B1) disease behavior in patients with Crohn’s disease according to the age at diagnosis (A), location (B), presence of perianal disease (C) and smoking status (D). A: PLogRank = 0.40, PBreslow = 0.62; B: PLogRank = 0.013, PBreslow = 0.002; C: PLogRank < 0.001, PBreslow < 0.001; D: PLogRank = 0.038, PBreslow = 0.051.
