Methods
	RCT Blinding:
	Location : Multicenter / Brazil Follow-up duration (days): 90
Inclusion criteria	18 years or older reported less than 8 days since onset of flu-like symptoms or chest computerized tomography scan consistent with COVID-19 at least one additional criterion for high risk: aged 50 years or older presence of pulmonary disease, specifically moderate or severe persistent asthma, chronic obstructive pulmonary disease, pulmonary hypertension, or emphysema diabetes requiring oral medication or insulin hypertension requiring treatment known cardiovascular diseases (congestive heart failure of any etiology, documented coronary artery disease, clinically manifest miscellaneous heart disease) symptomatic lung disease on chronic treatment history of transplantation obesity (body mass index ≥30 [calculated as weight in kilograms divided by height in meters squared]) immunocompromised status due to disease (eg, those living with HIV with a CD4 T-cell count of <200 cells/mm3, confirmed malignant neoplasm) immunocompromised status due to medication (eg, people taking 10 mg or more of prednisone equivalents a day) and patients with cancer
Exclusion criteria	Use of any of study drugs in 30 days prior to screening clinical evidence of progression of COVID-19 (ie, use of oxygen supplementation arterial oxygen saturation less than 94% use of noninvasive positive-pressure ventilation support) history of known life-threatening cardiac arrhythmias long QT syndrome known allergy to study drugs
Interventions

Primary outcome
	In the register Proportion of participants who were hospitalized for progression of COVID-19 disease [ Time Frame: Measuring during 28-day period since randomization (Intention to treat analysis) ]; Proportion of participants who died due to COVID-19 progression and/ or complications [ Time Frame: Measuring during 28-day period since randomization (Intention to treat analysis) ]
	In the report COVID-associated hospitalization and death

Risk of bias Overall The overall risk of bias reported in the table corresponds to the highest risk of bias for the outcomes assessed for the systematic review	Some concerns
General comment	In addition to the published article, the study registry and protocol were used in data extraction and risk of bias assessment. Enrollment into the hydroxychloroquine and lopinavir-ritonavir groups was discontinued in this platform study based on a decision from the independent Safety Monitoring Board following interim analysis results showing that it would be clinically irrelevant to recommend either treatment. The longest follow up in the report was 90 days, and in the registry 28 days. A number of outcomes in the registry were not reported (need for mechanical ventilation, shock and need for vasoactive amines, death due to pulmonary or cardiovascular complications). The definition used in the time to symptom resolution outcome in the paper (resolution of combined symptoms using the WURSS scale) was not pre-specified in the registry [Time to clinical improvement - Proportion of participants with clinical improvement, defined as normalization of temperature, Respiratory rate, SaO2, and cough relief (> 50% compared to baseline measured on a visual analog scale) in the last 72 hours] or in the protocol [Time until clinical improvement (up to 28 days), defined normalization of temperature, respiratory rate, SaO2, and cough relief (> 50 in relation to baseline measured on a visual analog scale) in the last 72 hours; Reduction in the perception of dyspnea (upper respiratory tract respiratory symptoms scale - WURSS-11) on days 0, 3, 7, 14 and 28 days)].
