Participant Flow

This was a remotely conducted study. Participants who completed the informed consent process but did not complete the enrollment process after receiving the study materials are "started" but are not considered to have "completed enrollment". This explains the discrepancy between "Started" and "Completed Enrollment"

Timeframe: Day 1 through Day 14 after enrolment

Population: mITT Disease Resolution cohort includes participants who meet the COVID-19 disease criteria on day 1. The symptom resolution rate was the primary outcome of the lopinavir-ritonavir adaptive platform arms (lopinavir-ritonavir and ascorbic acid).

COVID-19 symptoms are based on the following criteria: * At least TWO of the following symptoms: Fever (≥ 38ºC), chills, rigors, myalgia, headache, sore throat, new olfactory and taste disorder(s), OR * At least ONE of the following symptoms: cough, shortness of breath or difficulty breathing, OR * Severe respiratory illness with at least 1 of the following: * Clinical or radiological evidence of pneumonia, OR * Acute respiratory distress syndrome (ARDS), OR * LRTI, defined by resting SpO2\<93% sustained for 2 readings 2 hours apart AND presence of subjective dyspnea or cough Death or COVID-19-related hospitalizations will count as a failure to resolve symptoms.
