Abstract

HART, Department of Physics, Astronomy and Mathematics, University of Central Lancashire, Preston, UK presents a set of hypothetical but realistic scenarios in complementary medical research to demonstrate statistical errors that are common in clinical research.

Background

Statistical errors are common in clinical research.

Methodology

Scenarios, each containing at least one mistake typical of those made in analyses, are presented and discussed.

Results

Conclusion

Discussing the practical implications of observed effects is better than merely quoting p-values. ‘Data trawling’ should be avoided.
