Clinicians can use statistical analyses from observational studies to guide patient treatment choices. Quantitative data and predictive models enhance informed consent through clear outcome predictions.

Area of Science:

  • Clinical decision-making
  • Biostatistics
  • Health outcomes research

Background:

  • Clinicians recommend management schemes to patients.
  • Quantitative information from statistical analyses of observational studies is valuable for these recommendations.
  • While randomized controlled trials are optimal, nonrandomized studies can provide acceptable data with careful interpretation.

Purpose of the Study:

  • To highlight the utility of quantitative data from observational studies in clinical practice.
  • To emphasize the importance of multivariable predictive equations for individual patient outcomes.
  • To underscore the role of graphic presentations in patient communication and informed consent.

Main Methods:

  • Statistical analyses of observational studies.
