cord-315367-e0frkhe6	Du, Houwei	The effect of vascular risk factor burden on the severity of COVID-19 illness, a retrospective cohort study	2020-09-21		.txt	text/plain	3651	199	48	After adjustment for age, sex, and comorbidities as potential confounders, vascular risk factor burden remained associated with an increasing risk of severe COVID-19 illness. CONCLUSIONS: Patients with increasing vascular risk factor burden have an increasing risk of severe COVID-19 disease, and this population might benefit from specific COVID-19 prevention (e.g., self-isolation) and early hospital treatment measures. We therefore investigated the association between the number of vascular risk factors and severe COVID-19 disease in this observational retrospective study. Previous studies also showed individual vascular risk factors such as hypertension and diabetes were more frequent in severe COVID-19 patients [3, 14] . Association between vascular risk factor burden and severe COVID-19 illness adjusted for comorbidity, and sensitivity analyses using the E-value approach. Association between vascular risk factor burden and severe COVID-19 illness adjusted for laboratory and chest CT findings, and sensitivity analyses using the Evalue approach.	./cache/cord-315367-e0frkhe6.txt	./txt/cord-315367-e0frkhe6.txt
