> Interesting point about the data only being available on request. That doesn't seem like the authors are super proud of their work. Noting that data is available upon request isn't exactly strange But with an n=30 study, I'd expect a simple chart with the 15 control and 15 active participants on a plot. This would make it easy to see if one group had, for example, 1-2 outliers that skewed the average. In small scale studies like this, you could have something like 1 patient who stayed in the hospital for 60 days in one group while everyone else has a more typical ~9 day stay. That outlier would skew the results to an extreme. That's just one example. The real question is why they didn't include the simple chart, which would have allowed for us to see at a glance whether or not they had outliers.
