Fig. 3From: Zero-leak prediction during major lung resection aiming for minimal chest drainage duration: a retrospective analysisALE prediction. A A representative ALE scoring model developed in a fivefold cross-validation method. B ROC curve of the ALE risk scoring system (left) and a box plot showing its performance in fivefold cross-validation (right). C ALE prediction algorithm and patient flow. D The confusion matrix of the ALE prediction algorithm illustrated in (C). A dagger † denotes the true negative cohort, while double daggers ‡ denotes the false negative cohort. E Maximum leak flow (top) and leak duration time (bottom) in the false negative (FN) cohort†. AUC, area under the curve. ALE risk score, the total score of the ALE scoring model (A). npv, negative predictive valueBack to article page
