Results of logistic regression analyses predicting worsening disability, hospitalization, and death within 4 and 8 years. Unadjusted analyses predict outcome variables based on frailty status alone. Adjusted analyses include age, gender, minority status (White=0, Minority=1), income, hypertension, diabetes, arthritis, cancer, pulmonary disease, cardiac disease, IADL disability, self-rated health, Telephone Interview for Cognitive Status, and Center for Epidemiological Studies-Depression measure
