To systematically review the literature on female risk factors and risk of SAH.
Methods: We searched Medline and EMBASE for articles published between January 1985 and July 2011. For all studies fulfilling the predefined criteria, we obtained risk ratios (RRs) or odds ratios (ORs) with 95% confidence intervals (CIs) for female risk factors. We pooled crude and adjusted ORs (aORs) with a general variance-based random-effects method. We evaluated methodologic quality with the Newcastle-Ottawa Scale.
Results: We included 16 studies; 8 had good quality. Twelve studies had a case-control design, 3 studies had a longitudinal design, and 1 study had a case-crossover design. Read more
