SOD1 and Stroke: Multivariate logistic regression analysis of discrepant factors (Table 2) showed that age (95% CI, 1.031–1.129, P = .001), history of hypertension (95% CI, 1.045–5.354, P = .039), cholesterol (95% CI, 0.118–0.656, P = .003), intracerebral hemorrhage (95% CI, 0.013–0.656, P = .003), NIHSS score (95% CI, 1.083–1.209, P = .000), and subtypes of SOD and SUN (95% CI = 1.289–15.871, P = .018) were associated the increased risk of death within 90 days after stroke.
