Improving the evidence base in surgery: sources of bias in surgical studies

Jane M Young et al. ANZ J Surg. 2003 Jul.

Abstract

Clinical epidemiology, which is concerned with the application of epidemiological principles to patient care, provides the scientific basis for evidence-based medicine. The present paper reviews the epidemiological concepts of selection bias, measurement bias and confounding in surgical research and discusses ways in which these sources of bias can be minimized in surgical studies.
