Improving statistical quality in medical journals requires addressing common errors like p-value misinterpretation and confusion between statistical and clinical significance. Enhanced statistical education and collaboration are key to more accurate medical research reporting.

Area of Science:

Medical Statistics
Scientific Publishing

Background:

Medical literature frequently contains statistical errors.
Common errors include p-value misinterpretation and conflating statistical with clinical significance.

Purpose of the Study:

To review common statistical fallacies in medical publications.
To emphasize basic principles of statistical hypothesis testing.

Main Methods:

Review of frequent statistical errors in medical articles.
Emphasis on fundamental statistical hypothesis testing principles.

Main Results:

Identified frequent errors: p-value misinterpretation, statistical vs. clinical significance confusion, inappropriate test use, uncontrolled multiple testing, and post hoc hypothesis testing.

Overemphasis on p-values is a prevalent issue.

Conclusions:

Improving statistical quality necessitates addressing these identified errors.
Proposals include using statistical referees, fostering statistician-researcher collaboration, and statistical training for clinicians.
