The interpretations are stigmatising, dangerous and harmful for #LongCovid, especially as they are contested and not recognised by the whole scientific community and international associations. #afterJ20 🧵⏬
The @JAMAInternalMed study is considered biased by experts who have noted that in the seropositive group there are more false positives than true positives.
This problem has not been taken into account at all by the authors. methodsmanmd.medium.com/is-long-covid-…
This study also presents a major confirmation bias, based on the principle that a covid infection can only be demonstrated by a serology +, which poses a methodological, scientific and ethical problem.
A serology + should not condition multidisciplinary management.
We stand in solidarity with all #LongCovid patients, we believe you.
We support our fellow researchers & health professionals in France and internationally who have been working for months to find the causes of #LongCovid to take care of patients with dignity.
