  1. Mixed-effects model with centers as a random effect and considering a binomial distribution. AUC statistic (area under the curve) is 0.79 (95% CI 0.76 to 0.83), and Brier score is 0.18. P-values marked in bold indicate numbers that are significant on the 95% confidence limit. CI confidence interval; FiO2 fraction of inspired oxygen; PaO2 partial pressure of arterial oxygen
