Some concerns |
General comment | In addition to the published article, the trial registries and supplementary appendices were used in data extraction and assessment of risk of bias. Neither protocol nor statistical analysis plan was available. One primary outcome in the article reflect that in the registry (symptomatic COVID-19). The second primary outcome in the registry (severe COVID-19) is described as secondary in the article. The trial (n = 16876) achieved its target sample size (n = 16876). |
