Abstract
This monograph focuses on understanding statistical and clinical significance and
is one in a research and statistics series published by the statistical team of the
Journal of the Academy of Nutrition and Dietetics. The content covers the research questions, definition of clinical significance,
hypothesis testing, P values, effect sizes, sample sizes, CIs, power analyses, minimal clinically important
differences, and validity. This monograph concludes with a summary of the importance
of clinical and statistical results for credentialed nutrition and dietetics practitioners
to consider when assessing statistical and clinical significance. The assessment will
help readers make subjective clinical judgments in the application of research findings
based on their experience.
