All the abovementioned significant variables were forced into the multivariate model, and it was found that WFNS score (OR, 1.591; 95% CI, 1.022–2.493; P = 0.040), mFisher score (OR, 1.822; 95% CI, 1.063–3.134; P = 0.030) and serum AIM2 levels (OR, 2.389; 95% CI, 1.079–5.290; P = 0.032) independently predicted the occurrence of poor prognosis at 90 days after hemorrhagic stroke. Here, AIM2 is linked to hemorrhagic stroke.
