1-2 Taking care of old people on an outpatient basis is less costly than caring for them in nursing homes or hospitals, but health professionals have expressed concern about how well it is possible to predict clinical outcomes among people cared for on an outpatient basis. As part of an investigation of predictors of death in geriatric patients, Brenda Keller and Jane Potter compared survival in people aged 78.4 ± 7.2 (SD) years who scored high on the Instrumental Activities of Daily Living (IADL) scale and those who scored low. Based on the survival data in Table 11-8, is there a difference in the survival patterns of these two groups of people?
