What we have so far
Caffeine, paracetamol, standing up and the needle itself all move the number. More false positives here come from how the sample was taken than from any disease.
This star is on the map because the show intends to take the question apart properly — the trials, how it is actually tested, whether the thing sold is the thing studied. That work is not done yet, and nothing here should be read as a conclusion. When the investigation is published it will appear on this page.
