Abstract: In searching for biomarkers, one might maintain that it is prudent to have preliminary studies based on small samples. Given a satisfactory result, a large-sample follow-on study can then check reproducibility. However, is this two-fold approach, namely the decision to conduct the small study and the subsequent decision to spend significant resources on a large study, actually prudent? There is the risk that in the first study nothing at all might be discovered while in the second study the first results are not reproducible
