Effect of Convalescent Plasma Therapy on Time to Clinical Improvement in Patients With Severe and Life-threatening COVID-19: A Randomized Clinical Trial | JAMA | JAMA Network

Key Points

During the early days of the Coronavirus pandemic from January 2020 through March 2020, there was confusion, misinformation and disinformation coming from the media, China, CDC, and the White House.  There were only two credible sources for information Dr. Anthony Fauci and Dr. Deborah Birx. Numerous polls indicated trust in Fauci and Birx.  The White House frequently gave contradictory statements during live broadcasts.

What is the effect of convalescent plasma therapy added to standard treatment, compared with standard treatment alone, on clinical outcomes in patients with severe or life-threatening coronavirus disease 2019 (COVID-19)?

This randomized clinical trial that included 103 patients and was terminated early, the hazard ratio for time to clinical improvement within 28 days in the convalescent plasma group vs the standard treatment group was 1.40 and was not statistically significant.

Meaning  Among patients with severe or life-threatening COVID-19, convalescent plasma therapy added to standard treatment did not significantly improve the time to clinical improvement within 28 days, although the trial was terminated early and may have been underpowered to detect a clinically important difference.
