Figure 1 Interval development of the first episode of acute pancreatitis during the follow-up period. Patients with increased pancreatic sphincter pressure (SOD) were more likely to have at least one episode of acute pancreatitis during the follow-up evaluation compared with those with normal SOM (unadjusted HR, 3.5; 1.1–11.4) (P < .04). Among pancreatic SOD patients, the incidence of RAP during the follow-up evaluation was nearly identical between those randomized to BES (48.5%) and DES (47.2%) (P = 1.0). Similarly, there was no difference in RAP incidences between normal SOM patients randomized to sham (11.1%) or BES (27.3%) (P = .59). Note that most RAP events occurred within 30 months of randomization in all subgroups.
