Funnel plots of publication bias: (A) studies comparing GOS or mRS between CSF drainage and non-CSF drainage groups; (B) studies comparing the death rate between CSF drainage and non-CSF drainage groups; (C) studies comparing angiographic vasospasm prevention between CSF drainage and non-CSF drainage groups; (D) studies comparing symptomatic vasospasm prevention between CSF drainage and non-CSF drainage groups; (e) studies comparing cerebral infarction between CSF drainage and non-CSF drainage groups; (f) studies comparing shunt-dependent hydrocephalus between CSF drainage and non-CSF drainage groups. CSF = cerebrospinal fluid, GOS = Glasgow outcome scale.
