The observed disparities between the two groups were as follows: age (p < .001), outcomes (p < .001), stroke severity (p < .001), TOAST (p < .001), AF (p < .001), Hs‐CRP (p < .001), FBG (p = .024), Hba1c (p = .034), FIB (p < .001), and ALB (p < 0.001). This evidence concerns the gene CRP and atrial fibrillation.
