Table 2. The effect of male gender on the odds of severe attack in patients with acute biliary pancreatitis.
| Severity criteria | Men (n = 6,628), % | Women (n = 6,482), % | Adjusted odds ratio (95%CI)a | P values |
| Any | 15.7 | 14.2 | 1.08 (0.97–1.20) | 0.133 |
| Intensive care unit admission | 7.7 | 7.1 | 1.09 (0.96–1.25) | 0.163 |
| Organ failure | 8.0 | 7.9 | 0.94 (0.82–1.09) | 0.454 |
| Gastrointestinal bleeding | 3.8 | 2.4 | 1.44 (1.18–1.76)b | <0.001 |
| Local complications | 1.7 | 1.2 | 1.38 (1.05–1.82) | 0.017 |
a
Multivariable logistic regression using Generalized Estimating Equations models adjusting for age, year of admission, urbanization, hospital level, Charlson Comorbidity Index (0, 1, 2, 3+) and imaging studies (i.e., computed tomography and magnetic resonance imaging).
b
Peptic ulcer was forced into the model as an additional covariate because it is a cause of gastrointestinal bleeding.
