The results of the univariate logistic regression analysis indicate that age, admission NIHSS scores, EMT, coronary heart disease, atrial fibrillation, neutrophils counts, lymphocytes counts, NLR, and the level of lncRNA H19 in lymphocytes were all identified as independent risk factors associated with poor prognosis in patients with AIS (Table 2). The gene discussed is H19; the disease is atrial fibrillation.
