Patient and tumor parameters versus LI^*

	Statistic
Parameter	Broca LI	Wernicke LI
patient sex	F(1,47) = 4.84; p = 0.49	F(1,47) = 0.03; p = 0.87
patient age	H = 1.48, 1 df, p = 0.22	H = 1.67, 1 df, p = 0.20
tumor grade	F(1,47) = 0.20; p = 0.66	F(1,47) = 0.10; p = 0.75
tumor vol	H = 2.18, 1 df, p = 0.14	H = 8.26, 1 df, p = 0.004†
Broca LAD (from center of activation)	H = 7.44, 2 df, p = 0.02†	H = 2.64, 2 df, p = 0.26
Wernicke LAD (from center of activation)	H = 1.52, 2 df, p = 0.47	H = 7.53, 2 df, p = 0.02†

^*Comparisons between LI and sex or tumor grade were done using 1-way ANOVA. Comparisons between LI and age, tumor volume, and LAD were done by grouping the independent variables. Median split was performed on age and tumor volume. The LAD was grouped into 3 categories: LAD < 1 cm, 1–2 cm, and > 2 cm. Chi-square tests of association, Kruskal-Wallis test, and 1-way ANOVA were used.

^†Significant (p ≤ 0.05).
