Cumulative negative conversion rates of SARS-CoV-2 RNA in age subgroups during treatment
| During treatment | Age ≤ 60 Age > 60 | |||||
|---|---|---|---|---|---|---|

Note: Patients in every group were classified into age subgroups. The cumulative negative conversion rates were analyzed in the subgroup of age<60 and the subgroup of age≥60. *, P ≤0.05;**, P ≤0.01; ***, P ≤0.001.
