    Statistical methodology for clinical trials has advanced due to high-speed computation, improving data management and analysis. Promising developments in stopping rules address ethical constraints, though multiplicity issues remain challenging.

    Area of Science:

    • Biostatistics
    • Clinical Trial Methodology
    • Statistical Computing

    Background:

    • Clinical trial statistical methodology has significantly evolved with advancements in high-speed computation.
    • Data acquisition, management, and monitoring have been revolutionized, enhancing trial efficiency.
    • Statistical analysis has progressed from basic methods to sophisticated regression and covariance adjustment techniques.

    Purpose of the Study:

    • To explore the impact of computational advancements on statistical methodology in clinical trials.
    • To discuss the challenges and progress in areas such as sequential designs, stopping rules, and multiplicity.
    • To provide illustrative examples of these statistical issues in practice.

    Main Methods:

    • Review of statistical methodologies applied in clinical trials.
