Table 4.
Multivariate GEE Logistic Regression (n = 37 cases, 74 controls)
| Characteristic | OR (95% CI) | P |
|---|---|---|
| Current alcohol: yes vs. no | 3.22 (1.47, 7.07) | 0.004 |
| Mean Radiation Dose (Gy) (n = 37 cases, 74 controls) | 1.07 (1.01, 1.13) | 0.026 |
Keeping mean radiation dose constant, the odds of developing ORN for current alcohol drinkers are 3.22 times the odds for non-current alcohol drinkers. Holding current alcohol status constant, there is on average a 7% increase in the odds of developing ORN for a one-unit increase in radiation dose Gy.
