(A) Kaplan-Meier curve of progression to EPI after initial AP attack is shown. 6.6% (95% CI: 4.4%, 9.9%) were diagnosed with EPI within 1 year of initial AP attack; 9.4% (95% CI: 6.5%, 13.4%) within 2 years, there were diagnosed with EPI; 14.9% (95% CI: 10.5%, 20.9%) by 5 years. Within 6 years (through 12 years) from initial AP attack cumulative proportion with EPI was 18.0% (95% CI: 12.4%, 25.6%). (B) Kaplan-Meier curve of progression to diabetes mellitus after initial AP attack is shown. 2.1% (95% CI: 0.9%, 4.4%) were diagnosed with diabetes mellitus within 2 years of initial AP attack. Overall, 7.7% (95% CI: 4.2%, 14.1%) were diagnosed with diabetes mellitus within 6 years of initial AP attack (through the last follow-up).
