ALB and atrial fibrillation: Besides, when using the 3-month post-AIS mRS score as the outcome variable, multivariate logistic regression analysis(adjusted for sex, HDL-c, age, BMI, LDL-c, HGB, PLT, TG, ALB, BUN, hypertension, DM, smoking, AF, and the mRS score at admission) showed that each 1 g/L increase in fibrinogen is associated with an increase of 0.163 points in the 3-month post-AIS mRs score (β = 0.163, 95% CI: 0.058, 0.268; P = 0.002) (Supplementary Table S5).
