Table 3. Incidence rate and hazard ratio for inflammatory bowel disease stratified by severity of alcohol intoxication.
| Severity of alcohol intoxication | Event | Rate | Adjusted HR†(95% CI) |
|---|---|---|---|
| Non-alcohol intoxication cohort | 86 | 0.49 | Ref |
| Alcohol intoxication cohort | |||
| Mild (T1) | 33 | 1.21 | 1.76(1.13–2.73)** |
| Moderate (T2) | 28 | 5.12 | 6.83(4.13–11.3)*** |
| Severe (T3) | 33 | 14.14 | 19.9(12.1–32.8)*** |
| p for trend# | < .0001 | ||
| Number of hospitalizations due to alcohol intoxication during the follow-up time | |||
| 1 | 58 | 2.34 | 3.15(2.16–4.59)*** |
| 2 | 16 | 3.18 | 3.34(1.82–6.12)*** |

Rate, incidence rate, per 10 000 person-years; HR, adjusted hazard ratio; CI, confidence interval; T1, first tertile; T2, second tertile; T3, third tertile. Severity of alcoholism = (total length of hospital stay due to alcohol intoxication during the follow-up duration) ÷ (length of follow-up duration).
†Adjusted for age, sex, and each comorbidities.
# The p for trend was estimated by the Cox proportional hazard regression model.
**P < .01
***P < .001
