Abstract
Summary • We identified 11 randomised controlled trials published since June 2022 that were focused on Long COVID treatment or rehabilitation. Across two reports, we have now identified and assessed 25 trials published in 2022. • A majority of trials focused on evaluating treatments for people with persistent problems with their sense of smell (olfactory dysfunction). • Trial quality varied and inadequate reporting of methods often prevented a full assessment of the risk of bias. However, six trials were rated positively for at least 11 out of the 13 criteria that we assessed
