General comment |
In addition to the pre-print article, the trial registry was used in data extraction and assessment of risk of bias. Neither study protocol nor statistical analysis plan was available. Inclusion criteria in registry and the pre-print article differ slightly in that the pre-print article also included hypoxemic respiratory failure or acute clinical deterioration of pre-existing lung or heart disease. Some pre-stated primary (i.e., mean of oxygenation index delta) and secondary (i.e., mean time to negative PCR) outcomes were not reported. There were no substantive differences between the pre-print article and the trial registry in interventions. Patients considered at high risk of development of QT interval prolongation due to hydroxychloroquine were only randomized to the ivermectin or placebo arms. The trial was terminated due to a reduction in eligible participants. As a result, the target sample size was not achieved.
This trial was updated on July 28th, 2021 with data gained from contact with authors. |

General comment | The prospective trial registry was available. There were no differences between the published article and the registry in population or interventions. The study achieved its target sample size. No study protocol or statistical analysis plan was available. Outcomes reported were no relevant for the COVID-19 NMA. Consequently, no outcome data have been extracted for this study. |
