The results indicated that age (t = −13.62, P < 0.001), BMI (t = −3.60, P < 0.001), GHb (t = −6.67, P < 0.001), CRP (t = −3.55, P < 0.001), and the proportion of drinking (χ2 = 25.510, P < 0.001), emphysema (χ2 = 42.304, P < 0.001), chronic bronchitis (χ2 = 61.132, P < 0.001), hypertension (χ2 = 194.882, P < 0.001), high cholesterol (χ2 = 28.263, P < 0.001), and diabetes mellitus (χ2 = 168.476, P < 0.001) of participants in the stroke group were higher than those in the no stroke group. The gene discussed is CRP; the disease is pulmonary emphysema.
