    Area of Science:

    • Clinical trial methodology
    • Medical ethics
    • Biostatistics

    Background:

    • Schwartz and Lellouch distinguished between explanatory and pragmatic attitudes in clinical trials.
    • The concepts of individual and collective ethics are crucial in trial design.
    • Current practices often favor pragmatic approaches, such as intention-to-treat analyses.

    Purpose of the Study:

    • To explore the implications of explanatory versus pragmatic attitudes in clinical trials.
    • To examine the interplay between individual and collective ethics in research.
    • To evaluate the suitability of different analytical models for clinical trial data.

    Main Methods:

    • Review of foundational papers by Schwartz and Lellouch.
    • Analysis of the philosophical underpinnings of trial attitudes (explanatory vs. pragmatic).

    Related Experiment Videos

  • Discussion of ethical frameworks (individual vs. collective) in clinical research.

    • Main Results:

    • Pragmatic attitudes align with intention-to-treat analyses.
    • Emerging research investigates explanatory approaches with non-compliance adjustment.
    • Standard randomization methods offer a viable compromise between ethical perspectives.

    Conclusions:

    • The choice between explanatory and pragmatic approaches influences trial interpretation.
    • Reconciling individual and collective ethics is essential for robust clinical trials.
    • Further research into non-compliance adjustment models is warranted for explanatory trial aims.
