Only 90-day survival was multivariably evaluated. Linear covariates: NEWS: National Early Warning Score. ASA score: American Society of Anesthesiologists Physical Status score prior to this acute incident. Age measured in years. Categorical covariate: COPD chronic obstructive pulmonary disease, AUROC area under receiver operating curve. Unit OR: For each unit change in the predictor, the odds for being alive at the given time point improves by this factor
