^*For the final multivariable logistic regression, a backward-elimination variable selection method with the stay criterion of P < 0.15 was performed, starting with all the variables from the univariable logistic regression models in table 2 that had a P value < 0.25.

PAP – pulmonary artery pressure; FiO₂ – fraction of inspired oxygen; OR – odds ratio
