Comparison of CT findings in patients who had twice Chest CTs and corresponding RT-PCR tests and whose twice RT-PCR tests were ≤14 days apart.

	First chest CT( 19 patients)	Second chest CT(19 patients)	P value
Number of lobes affected	3(1,4)	5(3,5)	0.011*
Bilateral lung	13(68.4%)	17(89.5%)	0.125
More than 2 lobes affected	13(68.4%)	16(84.2%)	0.375
Median of total Lung Severity Score (25%,75%)	5(2,7)	8(4,11)	0.007*
Crazy-paving pattern	3(15.8%)	3(15.8%)	1.000
Peripheral distribution	16(84.2%)	13(68.4%)	0.375

Note: Data are median (IQR), n (%). p values comparing first Chest CT and second Chest CT results are from the McNemar-bowker test. *p values comparing first Chest CT and second Chest CT results are from Wilcoxon signed rank test, P value < 0.05.
