Area of Science:

  • Medical Research Methodology
  • Clinical Epidemiology

Background:

  • Evidence-based medicine (EBM) is a prevalent approach in academic medicine.
  • Concerns exist regarding the quality and objectivity of evidence used in EBM.

Purpose of the Study:

  • To highlight the prevalence of biases and confounding factors in medical research.
  • To emphasize the importance of transparent reporting of data and methods in EBM.

Main Methods:

  • Critical analysis of the limitations in current EBM practices.
  • Discussion of potential sources of bias in study design and interpretation.

Main Results:

  • Superficially convincing evidence in EBM is often compromised by hidden biases and design flaws.
  • These defects significantly hinder objective assessment of research findings.

Conclusions:

  • Adherence to rigorous scientific principles, including transparent data and methods disclosure, is crucial for reliable EBM.
  • Current practices often fail to meet the standards set by scientific methodology, undermining objective assessment.
