Treatment options for Severe acute respiratory syndrome‐related coronavirus‐2 (SARS‐CoV‐2) are limited with no clarity on efficacy and safety profiles. We performed a systematic review and meta‐analysis of studies on patients ≥ 18 years reporting data on therapeutic interventions in SARS‐CoV‐2. Primary outcome was all‐cause mortality and secondary outcomes were rates of mechanical ventilation, viral clearance, adverse events, discharge and progression to severe disease. Pooled rates and odds ratios (OR) were calculated. Twenty‐nine studies with 5207 patients were included. Pooled all‐cause mortality in intervention arm was 12.8% (95%CI: 8.1%‐17.4%). Mortality was significantly higher for studies using hydroxychloroquine (HCQ) for intervention (OR: 1.36, 95% CI: 0.97‐1.89). Adverse events were also higher in HCQ sub‐group (OR: 3.88, 95% CI: 1.60 – 9.45). There was no difference in other secondary outcomes. There is a need for well‐designed randomized clinical trials for further investigation of every therapeutic intervention for further insight into different therapeutic options.
