Results of Screening With Chest CT and SARS-CoV-2 RT-PCR

	Combined Screening (n = 1224)
	Chest CT	RT-PCR	Chest CT and RT-PCR
Positive screening result, no./total no.∗	8/1224	14/1224	18/1224
% (95% CI)†	0.7 (0.2–1.1)	1.1 (0.6–1.7)	1.5 (0.8–2.2)

^∗A positive chest CT result was defined as a CORADS 4-5. A positive result for the combined screening strategy was defined as a CO-RADS 4-5 and/or a positive RT-PCR result.

^†A 95% confidence interval was calculated based on 1000 bootstrap samples.

CI indicates confidence interval; CT, computed tomography; RT-PCR, reverse-transcriptase polymerase chain reaction.
