An analysis of the most
talked about covid-19 treatments

One year after the start of the covid-19 pandemic, doctors around the world continue to seek treatments to curb the disease that changed the life we knew. In this period, several clinical trials have been carried out that offer scientific evidence to confirm the efficacy or harm of the use of a drug or therapy with various patients who have suffered mild, moderate and severe symptoms of coronavirus infection.

In this special reporting project, produced in collaboration with the Epistemonikos Foundation, we analyzed the 38 most commonly used covid-19 treatments. To conduct this analysis, we created seven classifications, ranging from “highly effective” to “unsupported by science.” We developed these categorization levels to assess the usefulness of the main covid-19 treatments up to this point in time. We will update this information weekly as new scientific evidence becomes available.


Unsupported by science
This categorization pertains to treatments not currently being evaluated in scientific studies because, based on existing, established scientific knowledge, there is already sufficient information to warn of their risks or that it is unlikely they will be beneficial.
Ready to be abandoned
Category for treatments where there is sufficient evidential certainty that the treatment has either no benefit, the benefits do not outweigh the risks of treatment, or the benefit is minimal in relation to the high risk of the treatment.
Treatments which cannot be ruled out with certainty because they have some benefit, but the initial results of scientific study are not encouraging.
Treatments for which we cannot be sure of anything yet, because the certainty of the evidence is very low, the studies yield mixed results, or the data is unreliable.
We cannot yet be sure that the benefits outweigh the risks and costs of these treatments, but they yield encouraging initial results. These treatments are not ready for use yet, but further investigation is warranted.
Ready for use
For these treatments, the benefits outweigh the risks. The scientific evidence and data collected provide certainty that what happens in the studies accurately reflects what will happen through use with the larger, real-world population.
Highly effective
Our categorization for accessible, effective and safe treatments for which the evidence provides certainty that what happens in the studies reflects what will happen when the treatment is used with the larger, real-world population.
