Comparison of performance of risk stratification using IVA, risk stratification using three types of VA [FRS-based (5), SCORE chart-based (52), and cIMTave-based (46)], and risk stratification using chronological age for four types of data-partitioning protocols. (A) 5-fold data-partitioning, (B) 10-fold data-partitioning, (C) Jack-Knife data-partitioning, and (D) TT data-partitioning. FRS, framingham risk score; CA, chronological age; VA, vascular age; IVA, integrated vascular age; AUC, area-under-the-curve; TT, time-triggered.
