From: Acute cor pulmonale in Covid-19 related acute respiratory distress syndrome

  N patients with data Univariate analysis Multivariable analysis
Patient characteristics*
 Body mass index (kg/m2) 113 1.07 [0.996–1.14], p = 0.06 NR
Medical history*
 Diabetes 117 0.34 [0.15–0.78], p = 0.01 NR
 Chronic kidney disease 117 0.16 [0.03–0.71], p = 0.02 NS

 Pulmonary embolism 81 8.5 [1.63–44.33], p = 0.01 7.30 [1.32–40.29], p = 0.02
  1. Data presented as OR [95% CI]; OR—Odds Ratio, 95% CI—95% Confidence Interval, NS—not significant in the final model, NR—not retained in the final model; The multivariable model showed a good calibration as assessed by the Hosmer and Lemeshow goodness of fit test [X2(8 df) = 7.8, p = 0.45] and a fair discrimination as assessed by the receiver operating characteristics curve [area under the curve (AUC) 0.779; 95% CI 0.673–0.885; p < 0.0001]
