Table 3 Associations between variables at admission and one-year mortality (multivariable analysis) using Cox regression model. Kaplan–Meier survival estimates for mortality at 1 year after admission to the IMCU with regards to low (blue curve) or high (red curve) FIM scores. FIM scores were dichotomized into low (≤ 63) and high (> 63) FIM score

From: Functional Independence Measure score is associated with mortality in critically ill elderly patients admitted to an intermediate care unit
