Figure 1 Influence of smoking on the incidence of AP. There was a higher incidence of AP in patients with a smoking history vs those patients who had never smoked (*P = .07).

Figure 2 Cumulative incidence of AP. Patients with 1 or more risk factors (▴) had a significantly higher cumulative incidence of AP than patients with no risk factors (●).

Figure 3 Influence of smoking on the incidence of CP. Not one patient in the current smoking group developed CP. There was a significantly lower incidence of CP in patients with a smoking history compared with patients who had never smoked (*P = .02).

Figure 4 Cumulative incidence of CP. Patients with 2 or more risk factors (■) had a significantly higher cumulative incidence of CP compared with patients with 1 risk factor (▴). All patients without a risk factor (●) did not develop CP. Clinical Gastroenterology and Hepatology 2007 5, 952-958DOI: (10.1016/j.cgh.2007.03.020) Copyright © 2007 AGA Institute Terms and Conditions
