highly significantP = 0.011
Univariate analysis identified de novo IBD as a highly significant risk factor for rPSC ( P = 0.011; OR: 22, 95%CI: 1.54-314.31) and, in line with that, recurrence-free survival was substantially ( P ≤ 0.001) higher in patients with pre-OLT IBD (median 212 mo, 95%CI: 118-212) compared with de novo IBD patients (median 72 mo, 95%CI: 36-95) (Figure 3 ).
