Abstract
BackgroundSurvival is an important long-term outcome in prognostic research, including medical areas such as cardiovascular disease and oncology. We consider a model for the occurrence of vascular events in patients with symptomatic cardiovascular disease. Patient data were from the second manifestations of arterial disease (SMART) study. We go through the seven steps of the checklist for developing valid prediction models, as presented in Part II. The final model looks promising, but needs external validation to prove its actual value. The data set and R code is made available at the book's Web site.
