Note:—KPS indicates Karnofsky Performance Status.
↵a Data are number of patients, means [2 SDs] for normally distributed variables, or medians (interquartile ranges) for nonnormally distributed variables.
↵b P values were calculated using the Kruskal-Wallis test for nonparametric variables and the 1-way ANOVA for parametric variables.
