Table 3 shows the association between the baseline scores of the subdomains TR, DR, DRecog of the HVLT-R, and the clinical factors. The patients with KPS ≥ 80 had significantly higher TR scores (p = 0.0053 by Mann-Whitney U-test), higher DR scores (p = 0.012), and higher DRecog scores (p = 0.0078) compared to the patients with KPS ≤ 70. The patients aged ≤65 years also had significantly higher TR scores (p = 0.030) and higher DRecog scores (p = 0.031) compared to the patients aged ≥66 years, and they tended to have higher DR scores (p = 0.080). There were no significant differences in any HVLT-R subdomain scores among the WBRT dose groups, or among the different types of the cranial lesion.
