Multiple linear regression analysis was performed to determine possible predictors of variation in patients’ symptoms and HRQoL. The models were fit by an enter method, in which all variables were entered into the original model and then variables with p values of 0.05 were removed.
ASTA symptom scale score was used as a dependent variable to express symptom variation. The disease-specific ASTA HRQoL and the generic SF-36 component summaries (PCS and MCS) were used to express the variation in HRQoL. All reported p values are 2-sided, and a p value < 0.05 was considered statistically significant.
MCS = mental component summary; PCS = physical component summary; other abbreviations as in Tables 1 and 2.
