cord-309134-mxk8d9jd	Zhou, Yongxia	Cohort study of chest CT and clinical changes in 29 patients with coronavirus disease 2019 (COVID-19)	2020-06-26		.txt	text/plain	3752	209	56	The changes in the clinical and laboratory characteristics, imaging features, lesion-to-muscle ratio (LMR), and pulmonary inflammation index (PII) at baseline, 1–6 days, 7–13 days, and ≥ 14 days were compared. CONCLUSIONS: Lung lesion development on chest CT reflects the clinical time course of COVID-19 progression over 1–6 days, followed by clinical improvement and the resorption of lesions. This retrospective single-center cohort study attempted to disprove the hypothesis that chest CT findings at follow-up do not reflect the clinical time course of COVID-19. According to the Diagnosis and Treatment of Novel Coronavirus Pneumonia (trial version six) of China [8] , the discharge criteria were as follows: (i) afebrile for more than 3 days, (ii) significant reduction in respiratory symptoms, (iii) acute exudative lesions with substantial improvements on chest radiograph or CT, and (iv) two consecutively negative COVID-19 nucleic acid tests at least 24 h apart.	./cache/cord-309134-mxk8d9jd.txt	./txt/cord-309134-mxk8d9jd.txt
