After controlling for the effects of age, gender, aSAH severity, degree of bleeding, IVH, ICB, aneurysm location, and treatment, serum IL-6 levels were independently associated with poor outcome assessed by GOS at day 9 (OR = 0.1, p = 0.032, 95% CI = 0.01–0.8), day 11 (OR = 0.1, p = 0.03, 95% CI = 0.01–0.8), and day 13 (OR = 0.1, p = 0.02, 95% CI = 0.004–0.6) (see also Table S1). The gene discussed is IL6; the disease is aneurysm.
