30 day mortality unadjusted odds ratios (OR, left) of variables and final Generalised Estimating Equations (GEE) model with estimated 30-day mortality adjusted odds ratios (aOR, right). Variables coloured grey were not included in the final GEE model. An OR>1 represents increased occurrence of 30 day mortality. Abbreviations used: FiO₂, fraction of inspired oxygen; RR, respiratory rate; SpO₂, pulse oximetry; CRP, C-reactive protein; BMI, body mass index; CFS, clinical frailty scale. Blue variables were subsequently used in the final adjusted OR model.
