title: Statin use in spontaneous intracerebral hemorrhage: a systematic review and meta-analysis.
abstract: BACKGROUND
  Nonrandomized observational studies have been conducted to evaluate the effects of statins on clinical outcomes in patients with intracerebral hemorrhage. Several studies on the effects of statin administration in patients with intracerebral hemorrhage have been published recently, but the findings are inconsistent.
  
  
  OBJECTIVE
  To evaluate the effects of statins administered prior to hospital admission and during hospitalization on mortality and functional outcomes in patients with intracerebral hemorrhage.
  
  
  RESULTS
  We searched for relevant literature using multiple comprehensive databases and performed a systematic review and meta-analysis. Sixteen studies met our selection criteria. Preintracerebral hemorrhage statin use was not associated with mortality (odds ratio: 0·90, 95% confidence interval: 0·63-1·28). However, patients who used statins prior to intracerebral hemorrhage had a decreased risk of mortality at three-months following symptom onset (odds ratio: 0·47, 95% confidence interval: 0·32-0·68) and an increased probability of good functional outcomes (odds ratio: 1·49, 95% confidence interval: 1·01-2·19), as compared with those who did not. In-hospital use of statins was associated with a low risk of mortality (odds ratio: 0·34, 95% confidence interval: 0·26-0·44) irrespective of preadmission statin use or postadmission time-points. Additionally, we were unable to pool the data on statin withdrawal because of differences in study methodologies.
  
  
  CONCLUSIONS
  Although careful interpretation is necessary due to several study limitations, we have demonstrated that statin use in patients with intracerebral hemorrhage is likely associated with improved mortality and functional outcomes.
