Fig. 2

Visual assessment of model calibration for frailty index (FI). Predicted FI were derived from a model using the count-based physical frailty phenotype (PFP) as the only predictor (left panel) and a model using non-dichotomized PFP criterion predictors (right panel). Solid line represents the identity line. Dotted line represents a lowess smoother through the data points, showing good calibration (linear relation) between observed and predicted FI values for the model-based PFP
