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.

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 3,388 studies,
1,952 present results comparing with a control group,
1,766 are treatment studies, and
186 analyze outcomes based on serum levels. There are
44 animal studies,
90 in silico studies,
173 in vitro studies,
211 reviews,
and 146 meta analyses.
Please send us corrections, updates, or comments.
c19early involves the extraction of over 100,000 datapoints from
thousands of papers. Community updates
help ensure high accuracy.
Vaccines and treatments are complementary. All practical, effective, and safe
means should be used based on risk/benefit analysis. No treatment, vaccine, 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.
