In addition, a Korean team has evaluated the contribution of various factors, such as age, AD, chronic lung disease, stroke, hypertension, coronary vascular disease, dyslipidemia, chronic kidney disease, diabetes, and history of taking angiotensin II receptor blockers or ACE inhibitors, to the death rate of COVID-19 patients in a multicenter retrospective cohort, using multivariate logistic analysis, and found that only age, AD, and chronic lung disease are significant parameters for predicting COVID-19 non-survival (P < 0.05) [65]. The gene discussed is ACE; the disease is chronic lung disease.
