Univariate logistic regression analyses in dosimetric parameters

RLD=radiologic lung damage; AUC=area under the curve; ROC=receiver-operator characteristic; CLD=central lung distance; MLD=mean lung dose; Vx=percent of lung volume receiving more than X Gy.

^*Median value of each dosimetric factor in patients with RLD and those without RLD; ^†Logistic regression analysis; ^‡The cutoff point of the each variable was defined as a value that had lowest p-value by logistic regression analysis; ^§As the AUC of ROC value gets closer to 1.0, the parameter becomes more predictive of RLD.
