First they only tested 20 people, which is pretty low. And they don't seem to have tested anyone who wasn't previously a caffeine consumer. To be fair they conclude more study needs done.
- DryLabRebel 4y ago20 people is very low, presumably becuase the goal of the study was sleep effects, and they were using sleep labs, so I'd say that budget was a big issue here. No doubt they wanted to maximise sample size, which is why they used the same 20 individuals for both the test and control groups.
- BLKNSLVR 4y agoGenius! A "gateway" study to justify a larger, more scientifically thorough, and therefore much more expensive, study in which grant money is necessarily spent on lots of coffee!
- WJW 4y agoEvery study ever conducted ends with the recommendation that "more research is needed". Granted, not all studies are as self-evidently important as caffeine research :)
