Very little can be controlled for in studies like this. There are just too many factors to slice on, and before long you're just reading into noise.
- xattt 5y agoI think studies like this tend to overlook selection bias. What is typically omitted is that there is some degree of “tolerance” that’s needed to consume moderately caffeinated beverages. Individuals might avoid these drinks if they feel like they get negative effects (ie anxiety, palpitations, headaches) from them. I know this barely scratches the surface of the uncontrolled factors, but I wanted to throw this point out there.
