The majority (706, 89%) of the 789 contacted living subjects was interviewed (Figure 2). Non-interviewed subjects included those who refused (N = 55) and those who were unavailable for assessment due to cognitive or physical frailty or inaccessibility (e.g., institutionalization; N = 28). Baseline characteristics of these 83 not-interviewed individuals were not statistically different from those of the 706 interviewed subjects (all with FDR-adjusted p ≥ 0.05), with or without controlling for baseline age.
