Box plots of the differences in AEFpost (a) and decrease ratio (b) for response groups. The difference in AEFpost across response groups was statistically significant, demonstrated by ANOVA (p < 0.001), and the statistically significant difference was also observed in decrease ratio across response groups demonstrated by Kruskal-Wallis rank sum test (p < 0.001). P values for multiple comparisons were corrected by Holm-Bonferroni method. AEF = arterial enhancement fraction; PR = partial response; SD = stable disease; PD = progressive disease; ANOVA: analyses of variance
