    Healthy participant bias can distort results in case-control studies, particularly with low participation rates among controls.

  • 2

    In the breast cancer study, participation rates were 43.4% for controls and 64.1% for cases, highlighting the disparity.

  • 3

    Standardized mortality ratios (SMRs) indicated that overall mortality for controls was significantly lower than the reference population.

  • 4

    Higher education levels were associated with lower SMRs in both cases and controls, suggesting a link between education and health outcomes.

  • 5

    The study found a similar healthy participant effect in both cases and controls, making significant bias unlikely in this context.
