Second Surgery in Insular Low-Grade Gliomas

Table 4

Variable independently associated with tumor recurrence after surgical resection of insular LGGs in a multivariate proportional hazards analysis (Cox model). In the final model, the EOR remained the strongest independent significant predictor of TR after first surgery for insular LGG.
