  1. Feature Selection for the Imaging Model. This table presents the feature rankings determined by the MRMR algorithm and the Borda score. Rank 1 represents the most influential feature in clustering parameters regarding ECMO therapy, followed by Rank 2 and Rank 3. The three most influential and robust parameters, identified by the highest Wald scores from logistic regression, were selected for further evaluation (gray shaded). All the parameters were significantly correlated with ECMO therapy (p value < 0.001). The odds ratio (OR) indicates the direction and magnitude of influence. For example, a high atelectatic volume is strongly correlated with the need for future ECMO (OR = 1446.3), whereas a high normally ventilated volume is strongly correlated with no need for future ECMO (OR = 0.002). The parameters are explained in Table S1 in the supplement.
  2. CI: confidence interval; MRMR: minimum redundancy maximum relevance; OR: odds ratio; ECMO: extracorporeal membrane oxygenation; HU Hounsfield unit; CI: confidence interval.
