The impact of modelling approach on the association between frailty and short-term mortality. Simplified grouping used CFS < 4 as a reference, with vulnerability defined as a CFS = 4 and frailty as a CFS ≥ 5; CFS = 1 was used as a reference in the three other modelling approaches shown in the figure. Odds ratios obtained after dichotomisation of the CFS score are described in the text. The relationship between the CFS score and mortality was nonlinear in both models (p values < 0.01). Adjusted for age, sex, reason for admission to the ICU, and admission SOFA score
