Fig. 2From: Respective contribution of intensive care unit-acquired limb muscle and severe diaphragm weakness on weaning outcome and mortality: a post hoc analysis of two cohortsNonparametric classification and regression tree methodology (CART) selected variables as decision knots, ensuring optimal separation of patients successfully weaned from mechanical ventilation from those not successfully weaned (a) and optimal separation of survivors from non-survivors (b). MV, duration of mechanical ventilation prior to inclusion; S-ICU-DD, severe intensive care unit-acquired diaphragm dysfunction; ICU-AW, intensive care unit-acquired weaknessBack to article page
