Multivariate logistic regression analysis identified that age (aOR 1.041, 95% CI 1.013–1.071, p = 0.004), previous stroke (aOR 3.839, 95% CI 1.400–10.528, p = 0.009) were significant factors associated with the deaths of ischemic stroke, but CRP (aOR 0.993, 95% CI 0.986–0.999, p = 0.02) was associated with the deaths of other causes. Here, CRP is linked to Stroke.
