The declining prevalence of smoking and hypertension has been associated with the decrease of subarachnoid hemorrhage (SAH) incidence in the 21st century. Since these same risk factors are linked to SAH mortality, the case fatality rate (CFR) of SAH has potentially also decreased during recent decades. Thus, we conducted a systematic review to address SAH CFR changes over the last 40 years.
