CHEMISTRY WITH CONFIDENCE - SHOULD CLINICAL-CHEMISTRY REQUIRE CONFIDENCE-INTERVALS FOR ANALYTICAL AND OTHER DATA

Confidence intervals are not commonly provided with analytical or othe r data reported in Clinical Chemistry although P values are. However, confidence intervals provide an explicit demonstration of the directio n and magnitude of uncertainty and are intuitively easy to grasp, unli ke P values. It is therefore argued that the Journal should adopt a po licy requiring the provision of confidence intervals. Such a policy wo uld improve the statistical rigor of Journal reports.
