Chemistry with confidence: should Clinical Chemistry require confidence intervals for analytical and other data?

AR Henderson
Department of Clinical Biochemistry, University Hospital, University of Western Ontario, London, Canada.

Confidence intervals are not commonly provided with analytical or other data reported in Clinical Chemistry although P values are. However, confidence intervals provide an explicit demonstration of the direction and magnitude of uncertainty and are intuitively easy to grasp, unlike P values. It is therefore argued that the Journal should adopt a policy requiring the provision of confidence intervals. Such a policy would improve the statistical rigor of Journal reports.
