Meta-analysis investigating the association between meningioma location and postoperative seizures. In examining the likelihood of postoperative seizures among skull base versus non–skull base meningiomas, no significant relationship between tumor location and seizures was observed. The effect size for each study is represented as the OR of factors associated with preoperative seizures (a larger OR indicates greater likelihood of seizures), with proportional study weight estimated by the size of each point. Error bars represent the 95% CI. The size of each point estimates proportional study weight, and the vertical dashed line represents OR = 1.
