↵a Mode of presentation was analyzed as a global model categorizing presentations as cranial nerve deficit, headache, incidental, neurologic deficit (noncranial nerve), recanalization of previously treated aneurysm, or other. Global model not significant; individual predictors also not significant (odds ratios and P values not shown).
