- The breakdown of patients recruited by stratified dimensional sampling. Overall, we will attempt to equally recruit patients from the unique strata for each domain evaluation in this study. Patients health status will be determined by the ECOG Performance status . We assume that all patients being seen at the Lifetime Cancer Screening and Prevention center will be of good to fair health, while patients seen at the Cancer hospital will range from good- to- fair to poor health status. Gender is also used as a sampling factor because there are modules within this web-based health history forms that are specific for each gender.
