Follow-up duration (days): 28
|Inclusion criteria||Adult patients aged 18 years or more were eligible if they had mild symptoms of Covid-19 (i.e., fever, acute cough, shortness of breath, sudden olfactory or gustatory loss, or influenza-like-illness) for less than five days before enrollment, were non-hospitalized, and had a positive PCR test for SARS-CoV-2 in the baseline nasopharyngeal swab.|
|Exclusion criteria||Patients were excluded if they had moderate-to-severe Covid-19 disease (e.g., required hospitalization), any condition that might preclude following the study procedures safely (e.g., mental disability), known allergy or hypersensitivity to study drugs, known retinal and severe liver or renal diseases, history of cardiac arrhythmia, known QT prolongation or other diseases that could be exacerbated by study drugs (e.g., psoriasis), active treatment with medications that are contraindicated with study drugs, or known HIV infection. Females who were pregnant (verbally declared or positive pregnancy test) or breastfeeding were also excluded.|

In addition to all available versions of the published article, the study registry was used in data extraction. |
Quote: "This trial was a secondary study of the Barcelona Postexposure Prophylaxis Study against SARS-CoV-2 (BCN PEP CoV-2 Study) registered in ClinicalTrials.gov, NCT04304053"
No protocol or pre-specified statistical analysis plan are available. There was a change in the protocol for the intervention.
Quote: "Initially, the protocol included the use of HCQ and cobicistat-boosted darunavir (DRVc) combined treatment, but it was adapted to HCQ alone after the recommendation of the pharmaceutical company not to use DRVc for the treatment of Covid-19 due to lack of activity in-vitro and the negative results in human clinical trials of closely related HIV protease inhibitors."
Safety analysis was performed. Quote: "Twenty SAE were reported, 12 in the control arm and 8 in the intervention arm, none of them related to HCQ (Table S3)."
