Fig. 2From: Interpretable classifiers for prediction of disability trajectories using a nationwide longitudinal databaseHeterogenous disability trajectory classes of older adults with complete information at least three waves (n = 4,149). Disability score (0–28) was measured by the sum score of BADL (0–12) and IADL (0–16). Three trajectory classes were identified: progressive class, high-onset class, and normal class. Each trajectory represents the mean change pattern of the 3 classesBack to article page
