Notes:
a
95% CI for mean difference.
b
Significant at α≤0.05. The dose of radiotherapy that was delivered to 20%, 30%, or 50% of the esophageal volume was classified as D20, D30, or D50, respectively. Bold value indicates D50 in group 1 (ethyol given) represents a significant increase in dose to 50% of the esophagus volume at which point opiates were used.
