Cumulative negative conversion rates of SARS-CoV-2 RNA in the subgroups of interval time during treatment.
| During treatment | Interval time ≤4 days | Interval time >4days | ||||
|---|---|---|---|---|---|---|
| Control group (n=276) | Treatment group (n=320) | P value | Control group (n=63) | Treatment group (n=94) | P value | |
| Cumulative negative conversion rate, No./Total (%) | ||||||
| At Day2 | 20/276(7.25) | 27/320(8.44) | 0.59 | 13/63(20.63) | 26/94(27.66) | 0.32 |
| At Day3 | 38/276(13.77) | 75/320(23.44) | 0.03* | 22/63(34.92) | 54/94(57.45) | 0.006** |

Note: The interval time is the time between the onset of illness and randomization. Patients in every group were classified into subgroups according to interval time. The cumulative negative conversion rates were analyzed in the subgroup of interval time≤4 days and the subgroup of interval time>4 days. Among 858 patients, 753 patients who can provide the interval time from onset of illness to randomization were classified into subgroups according to interval time. *, P ≤0.05; **, P ≤0.01.
