Multivariate Logistic Regression Analysis for Baseline Characteristics
| Characteristics | Adjusted OR [95% CI] | |
|---|---|---|
| BMI (per 1 kg/m2 increase) |
1.05 [1.03, 1.07] | < 0.001 |
| ALT (per 10 IU/L increase) |
1.05 [1.02, 1.09] | 0.004 |
| Current smoking | 1.15 [1.01, 1.32] | 0.035 |
| Acid reflux symptoms | 2.72 [2.22, 3.33] | < 0.001 |
| Hiatal hernia | 2.32 [2.01, 2.69] | < 0.001 |
| Atrophic gastritis | 0.66 [0.58, 0.74] | < 0.001 |
aUnit ORs are presented for continuous variables.
BMI, body mass index; ALT, alanine aminotransferase.
A higher OR indicates a higher risk of having reflux esophagitis given each characteristic.
