Predicted 5- to 10-year distant recurrence (DR) risk since random assignment and Clinical Treatment Score post–5 years (CTS5) values for the combined data set. Solid vertical lines indicate cutoff points for risk groups. Arrows indicate the CTS5 and equivalent 5- to 10-year risks of a patient age 54 years with a 12-mm, node-negative, grade 2 tumor. Using the formula CTS5 = 0.438 × nodes + 0.988 × (0.093 × size − 0.001 × size2 + 0.375 × grade + 0.017 × age), her CTS5 score is 2.61 and her 5- to 10-year risk of DR is 3%.
