The Limits of the RCT in Physiology

People don't fit into RCTs we are not homogeneous populations. In many things in physio we don't know enough about the underlying mechanisms behind what we're doing to actually account for the known confounders because it hasn't been studied yet. We still have a lot of holes to fill but back to your question about balance it definitely is balance and you know when I was a new grad it was sort of the start of the research era right?
