Primary outcome | |
In the register Clinical changes in COVID-19 symptoms [ Time Frame: 4 weeks ] The primary endpoint will be the proportion of patients who show a change in symptoms 28 days after the administration of the first dose. A responding subject is defined as a subject with improvement in at least 2 categories on the 8-point World Health Organization (WHO) ordinal scale of clinical status or a subject who is discharged. | |
In the report Proportion of patients that showed improvement 28 days after the administration of the first dose of at least two categories based upon the WHO ordinal clinical status scale or hospital discharge | |

General comment |
In addition to the pre-print article, the study registry was used in data extraction and risk of bias assessment. Neither study protocol nor statistical analysis plan was available. A supplementary appendix is referred to in the pre-print article, but this was not available. The study achieved the pre-specified target sample size. Efficacy outcomes used mITT which resulted in three fewer participants in the treatment group than the target sample size. Some laboratory measurements described as being done were not reported, but may be in the supplementary appendix. There is no change from the trial registration in the intervention and control treatments.
On 19th of April, 2021, this study was updated based on the published report. |
