I'm surprised (horrified?) that a control group's DNA deteriorates significantly enough in such a short trial to use as a comparison. #entropy

The study is likely useless since eight weeks total does not constitute long-term effects. You’d need to do this with a larger sample size over years to get reliable data.
8 weeks is not unusual for a study like this (randomized and controlled). Almost no study where researchers tell participants what to do will be longer. Epidemiological studies, of which there are many on coffee, do have more subjects over years, but rely on self-reported data.
Central Europe. Maybe they took the 50 or so older people still living in the Tschernobyl exclusion Zone?
