  1. Numerical variables were presented as mean ± standard deviation. Categorical variables were expressed as counts (percentage). Numerical variables were analyzed by Mann-Whitney U-test or unpaired Student t test. Categorical variables were analyzed by chi-square test or Fisher exact test. n indicates number of patients; WFNS, World Federation of Neurological Surgeons.
