This very powerful technique allows researchers to control for the effect of multiple predictor variables and generate “adjusted” survival curves. It generates a risk estimate analogous to the RR, the hazard ratio, and corresponding confidence intervals. This technique is widely used in the medical literature. It is discussed in more depth in a later chapter. 1. Limitations of Multivariate Techniques It should be kept in mind that multivariate regression techniques, while extremely useful, still have limitations.

If the risk estimate relative to the cases is similar across the different control groups, the conclusion is more likely to be correct. Finally, if the cases are drawn from a population-based registry, it is a common practice to select controls from the general population within that geographic area. Sample size estimation is an important part of the design phase of any study, and observational designs are no different. The sample size requirement is often a major factor in determining feasibility of a study.
