chiming in to agree here. for something along the lines of basic organ system operation like blood flow, you need only a small sample to show that there is an effect. example: a sample of 12 people would be more than enough to prove that people bleed if they are cut. you could look at a sample of 10k people just to be sure -- but you're not going to learn anything new. the experimental measurement of the variable is too high level. the point of this study is to corroborate past research and provide another avenue of future investigation. if a future study finds that the inverse is true, we now have reason to be suspicious of that study's conclusions.
