Random effects meta-analysis of all studies (pooled effects, all stages). Treatments with ≤3 studies with distinct authors or with <50 control events are shown in grey. Pooled results across all stages and outcomes depend on the distribution of stages and outcomes tested - for example late stage treatment may be less effective and if the majority of studies are late stage this may obscure the efficacy of early treatment. Please see the specific stage and outcome analyses. Protocols typically combine multiple treatments which may be complementary and synergistic, and the SOC in studies often includes other treatments. 0.6% of proposed treatments show efficacy in clinical studies.

Physician results with early treatment protocols compared to no early treatment. These results are subject to selection and ascertainment bias and more accurate analysis requires details of the patient populations and followup, however results are consistently better across many teams, and consistent with the extensive controlled trial evidence that shows a significant reduction in risk with many early treatments, and improved results with the use of multiple treatments in combination.

We aim to cover the most promising early treatments for COVID-19. We use pre-specified effect extraction criteria that prioritizes more serious outcomes, for details see methods. For specific outcomes and different treatment stages see the individual pages. Not all treatments are covered here, effectiveness has been reported for many other treatments in studies. Of the 4,873 studies, 2,420 present results comparing with a control group, 2,215 are treatment studies, and 205 analyze outcomes based on serum levels. There are 89 animal studies, 168 in silico studies, 301 in vitro studies, 350 reviews, and 223 meta analyses.
Please send us corrections, updates, or comments. c19early involves the extraction of 100,000+ datapoints from thousands of papers. Community updates help ensure high accuracy. Treatments and other interventions are complementary. All practical, effective, and safe means should be used based on risk/benefit analysis. No treatment or intervention is 100% available and effective for all current and future variants. We do not provide medical advice. Before taking any medication, consult a qualified physician who can provide personalized advice and details of risks and benefits based on your medical history and situation. FLCCC and WCH provide treatment protocols.
