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 4,804 studies,
2,401 present results comparing with a control group,
2,198 are treatment studies, and
203 analyze outcomes based on serum levels. There are
89 animal studies,
167 in silico studies,
297 in vitro studies,
343 reviews,
and 218 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.
