Methods
	RCT Blinding: Unblinded
	Location : Single center / China Follow-up duration (days): 28
Inclusion criteria	(1) 18-65 years of age; (2) diagnosed as mild to moderate COVID-19; and (3) willing to sign informed consent.
Exclusion criteria	(1) were pregnant or breastfeeding women; (2) had aspartate aminotransferase (AST) or alanine aminotransferase (ALT) >5 x upper normal limit, creatinine clearance <50 ml/min (Lu and Dong, 2019); (3) were allergic or intolerant to therapeutic drugs; (4) were HIV-positive patients; (5) had severe heart disease, brain disease, lung disease, kidney disease, neoplastic disease, or other systemic diseases, which may have had the potential to influence patients' adherence to the prescribed antiviral regimens; and (6) withheld informed consent.
Interventions

	Control Ribavarin+Interferon alpha (2 g/400-600 mg/ 5 MIU or 50mg) Co-Intervention: Standard care Duration : 14 days
	Treatment 3 Lopinavir+Ritonavir+Interferon alpha (400 mg/100 mg/ 5 MIU or 50mg) Co-Intervention: Standard care Duration : 14 days
Participants
	Randomized 101 participants n₁=32/ n₂=33/ n₃=36
	Characteristics of participants N=101 Mean age : 42.1 46 males Severity : Mild: n=0 / Moderate: n=101/ Severe: n=0 Critical: n=0
Primary outcome
	In the register The time to 2019-nCoV RNA negativity in patients
	In the report The difference in the interval from baseline (initiation of antiviral treatment) to SARS-CoV-2 nucleic acid negativity by nasopharyngeal swab among the three antiviral treatment groups, with each of these two tests at least 24 h apart.
Documents available	Protocol Yes. In English Statistical plan Yes Data-sharing stated Yes
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 all available versions of published article, the study registry and protocol were used in data extraction and risk bias assessment. Sample size specified in the registry was not achieved due to "scarcity of appropriate patients to recruit". There is no change from the trial registration in the intervention and control tratments. There is no change from the trial registration in primary and secondary outcomes. The trialists used as primary outcome "SARS-CoV-2 nucleic acid negativity" defined as "presence of negative SARS-COV-2 results in at least two consecutive nasopharyngeal swabs by reverse transcriptase polymerase chain reaction (RT-PCR), with an interval of at least 24 h between the two time points of swab-taking" which we interpreted as "negative conversion".
