I would like to see this study replicated as the sample size of 22 seems low, and I have a strong suspicion nutrition plays a very large role as covariate here.

I would like to see this study replicated as the sample size of 22 seems low, and I have a strong suspicion nutrition plays a very large role as covariate here. Just not sure how generalizable this is. Ive been doing some data analysis internship for a similar study but more brain vs circadian cycles. The human data is often messy and does not replicate. The clonal mouse studies data is often more consistent, and what Im building an in silico model for.
