The observed disparities between the two groups were as follows: age (p < .001), gender (p = .002), stroke severity (p < .001), TOAST (p < .001), smoking (p < .001), atrial fibrillation (p < .001), Hs‐CRP (p = .020), FBG (p = .023), FIB (p < .001), ALB (p < .001), and FAR (p < .001). The gene discussed is MAP3K14; the disease is atrial fibrillation.
