Flaws in the published research on long COVID are likely to have exaggerated the true risks of developing the condition, according to a study.

Researchers from the University of California San Francisco, University of Southern Denmark, Public Health England, and St George's University of London, say issues including broad definitions and a lack of appropriate – or any – comparison groups in studies looking at the incidence, prevalence, and epidemiology have distorted the risks.
