Considering that the randomization performed in the past remains after 22 years of follow-up; the individual records from this trial will be linked with two nationwide health datasets: COVID-19 cases notified in the Brazilian Influenza Surveillance System (SIVEP/Gripe) and the COVID-19 deaths registered in the Brazilian Mortality Information System (SIM) databases; from January 27; 2020; onwards.", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
