Note. CRT = cranial radiation therapy; RR = relative risk. All models were adjusted for age at 2003 follow-up, age at diagnosis, gender, and race. RRs of 1.0 indicate the reference group for categorical variables.

^an = 5,779 observations in the model for ever-smokers.

^bn = 5,673 observations in the model for current smokers.
