Fig. 4From: Prognostic value of oxygen saturation index trajectory phenotypes on ICU mortality in mechanically ventilated patients: a multi-database retrospective cohort studyThe subgroup analysis of the association between OSI-trajectory based phenotypes and ICU mortality. Almost subgroups showed a significant correlation between the dynamic OSI trajectories and ICU mortality. ARDS: acute respiratory distress syndrome; APS-III score: Acute Physiology III score; NMBAs: neuromuscular blockades; OSI: oxygen saturation indexBack to article page
