Figure 4. Subgroup analyses for primary outcome Subgroup analyses for good outcome (GOS 5), RR=risk ratio. (A) Subgroup analyses for good outcome (GOS 5) in age, Hunt-Hess, clot size and surgical procedure, gender and aneurysm size showed no difference between groups. (B) Heterogeneity test showed no heterogeneity in age, Hunt-Hess, clot size and surgical procedure subgroups (I2=0); gender (I2=9%) and aneurysm size (I2=28%) subgroups had no significant heterogeneity.
