Attributable risk is one of the most popular indices for measuring the risk of a factor in the development of disease in epidemiology and biomedical science. The usual practice for a multilevel risk factor is to determine the category specific attributable risk at different levels reference to a base level. When the risk factor is significant, it is also important to evaluate the risk of the factor at different levels reference to intermediate base levels. This information would contribute policy makers and health practitioners in detecting important categorization of the risk factor at a multilevel setting. This paper investigates confidence interval estimate of attributable risk for a multilevel exposure factor using intermediate base levels under a cross-sectional study and provides an application using a real-life example.
