Bivariate analysis showed significant differences (P < 0. 05) in the proportion of female patients, hypertension, Hunt-Hess Scale, modified Fisher Bivariate analysis showed significant differences (P < 0. 05) in the proportion of female patients, hypertension, Hunt-Hess Scale, modified Fisher score, Hijdra scores, M-Hijdra scores, and presence of hematoma (diameter≥1 cm) between groups. Statistical comparisons between continuous and categorical variables were performed using Student t-test (∗∗) and chi-squared test (‡).
