Table 2.

Univariate analyses of visual field defect ratio (VFDR) with baseline covariates. VFDR did not differ significantly by treatment arm; of potential covariates, only age of diagnosis significantly negatively correlated with VFDR. SRS = stereotactic radiosurgery; ATL = anterior temporal lobectomy; Ip:Con = surgery ipsilateral or contralateral to language dominance. a P value from Mann-Whitney U test; b Spearman correlation coefficient (Corr Coeff) with P value.
