Cumulative negative conversion rates of SARS-CoV-2 RNA during treatment

During treatment	Control group (n=368)	Treatment group (n=490)	P value
Cumulative negative conversion rates, No./Total (%)
At Day2	34/368 (9.24)	68/490 (13.88)	0.04*
At Day3	61/368 (16.58)	158/490 (32.24)	<0.001***
At Day4	133/368 (36.14)	252/490 (51.43)	<0.001***
At Day5	223/368 (60.60)	322/490 (65.71)	0.12
At Day6	257/368 (69.84)	381/490 (77.76)	0.008**
At Day7	304/368 (82.61)	427/490 (87.14)	0.06

Note: The levels of SARS-CoV-2 RNA were tested by real-time PCR every day after patients were treated. The cumulative negative conversion rates of SARS-CoV-2 were recorded every day. *, P ≤0.05; **P ≤0.01; ***P ≤0.001.
