  1. aThe cell values demonstrate the whole circumferential length of esophagus receiving a dose greater than a certain dose per fractionation. For example, “2.7Gy = 13 cm” demonstrated that the whole circumferential length of esophagus received 2.7Gy per fraction or more was 13 cm
  2. br” refers to the correlation coefficient calculated by Spearman’s testing
