Yep. Itís been cited a lot and itís probably the best out there. Regardless, every study design has multiple limitations, such as but not limited too:
- self interest of designer
- study design
- experience of subjects
- measurement error (Dexa measures water with lbm, for example)
- age of subjects
- compliance of subjects
- calories consumed
- effort of subjects
- individual responses
- Data mining
Itís nearly impossible to account for all the potential confounders. Overall, who knows. Like many have said, find the minimal amount you can recover from and make progress on and take it from there.
