Notes. Bootstrap estimates and 95% bias-corrected confidence interval for indirect effects of personality traits on ADL incidence through physical activity, disease burden, depressive symptoms, self-rated health, handgrip strength, falls, and smoke controlling for age, sex, education, and race when available.
