Picking up the opening post: that is the part I would want checked first.

Posting a small dataset on network meta-analysis. It is mine, it is uncontrolled, and the method is stated so it can be discounted appropriately.
What I would like is not agreement but a second dataset collected by someone with no stake in mine. If one exists I would rather read it than argue for this one.
