Abstract:
OBJECTIVETo evaluate the contribution of individual risk factor to a disease on someone with several risk factors.
METHODSA method based on epidemiological theory and Bayes' theorem was established to measure the contribution of individual risk factor, using the relative risk (RR) or odds ratio (OR) value obtained from population-based cohort studies or meta-analysis.
RESULTSThe proportional contribution for individual risk factor to disease in one person can be measured or estimated.
CONCLUSIONThis method can be applied to risk assessment in a patient with more than one risk factor, and the results also contribute to our etiological study and clinical decision-making strategy.
