  1. The comparisons between the two groups for the primary endpoint and for the secondary endpoints (absolute decrease of WHO-CPS at day 28 from baseline day 1, absolute decrease of WHO-CPS at day 14 from baseline day 1 and absolute decrease of SOFA score at day 7 from baseline day 1) were performed by multivariate ordinal regression analyses. The time to hospital discharge and the time to ICU discharge were compared by univariate Cox regression analysis. The exact P value for the comparison of WHO-CPS scores by day 28 is 7.7 × 1010, and the exact P value for the absolute decrease of WHO-CPS score at day 28 from baseline day 1 is 1.4 × 10−8.
