In this single-center study, aiming to further identify the value of chest CT in clinical management of COVID-19, we evaluated the association of initial chest CT findings obtained at admission with severity and clinical outcomes in older patients with COVID-19. In the survival (n = 52) and death (n = 46) groups, the patients were sub-grouped based on the time interval between symptom onset and the "initial CT" scan: subgroup1 (interval ≤ 5 days), subgroup2 (interval between 6 and 10 days), and subgroup3 (interval > 10 days). In subgroup1 and subgroup2, patients underwent CT scans within 10 days after symptom onsets, where the mean score of "initial CT" was statistically higher in the death group than in the survival group.	./cache/cord-301687-wadf3c3i.txt	./txt/cord-301687-wadf3c3i.txt
