ME/CFS Science @mecfsscience.org · 08/08/20261) 🇩🇪 In the CoCo-Fakt study at Cologne and Ausberg, patients with Long Covid reported doing more and more intense physical activity than controls who had COVID-19 but no long term symptoms. The researchers expected the opposite. 2105
ME/CFS Science @mecfsscience.org · 08/08/20262) There are some big limitations though: this was an online survey and the physical activity was measured retrospectively, so there was a big risk of recall bias. 74% reported doing at least 150 min per week, which is more than the national average of 48%. 130
ME/CFS Science @mecfsscience.org · 08/08/20263) Another big issue is the low response rate. More than 100.000 email addresses were contacted but 80% did not respond, and many others dropped out for other reasons. The final sample consisted of 5413 participants of which 10% reported long term symptoms. 140
