Patients were dichotomized into lower pain (score: 0 or 1) and higher pain (score: 2 or 3) groups. Logistic regression analysis resulted in odds ratio = 3.1 (95% confidence interval [CI]: 1.2–7.9; p = 0.015) and odds ratio = 10.2 (95% CI: 3.6–29.2; p < 0.001) for esophagus pain and throat pain, respectively. This means that for each increase in 1 Gy of fractional organ at risk mean dose, the estimated odds of experiencing higher pain increase by a factor of 3.1 and 10.2, respectively.
