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)]. |
