Univariate and Multivariate Analyses of Potential Factors Associated With Tumor Size Reduction

	Univariate Analysis P Value	Multivariate Analysis P Value
Age (≤ vs > 65 y)	.027	.055
Sex (male vs female)	.432
Baseline body weight (< vs ≥ median)	.075	.035
Baseline ECOG performance status (< vs ≥ 1)	<.001	.007
Histology (follicular vs papillary)	.359
Prior VEGF-targeted therapy (0 vs 1)	.168	.459
Baseline tumor size (< vs ≥ median)	<.001	<.001

P values were estimated with linear regression model. Factors with univariate P < .2 were included in the multivariate model.
