Table 2 Binary logistic regression models comparing predictors of (a) institutionalization, (b) hospitalisation and (c) death. Models 2 (a, b, c) include the Clinical Frailty Scale, model 3 (a, b, c) the RISC score, with the significance value of model change denoting increased predictive accuracy of the model relative to models 1 (a, b, c) respectively
