    Standard deviation (SD) and standard error (SE) are common in medical papers. This review clarifies their correct use in reporting research data and estimating population parameters to improve clarity in biomedical reports.

    Area of Science:

    • Biostatistics
    • Scientific Communication
    • Medical Research Methodology

    Background:

    • Standard deviation (SD) and standard error (SE) are frequently employed in biomedical literature.
    • These statistical measures are utilized for both descriptive statistics (summarizing data) and inferential statistics (estimating population parameters).

    Purpose of the Study:

    • To review the application and misapplication of SD and SE in prominent medical journals.
    • To provide recommendations for enhancing the clarity and accuracy of SD and SE reporting in scientific publications.

    Main Methods:

    • Analysis of statistical reporting practices in selected authoritative medical journals.
    • Identification of common errors and ambiguities in the use of SD and SE.

    Main Results:

    • Observed inconsistencies and potential misuse of standard deviation and standard error in published biomedical research.
    • Identification of specific areas where clarification of SD and SE usage is needed.

    Conclusions:

    • Clearer guidelines and consistent application of standard deviation and standard error are essential for accurate interpretation of biomedical data.
    • Implementing suggested clarifications will improve the rigor and understanding of statistical reporting in medical publications.
