Fig. 4From: Lung tissue expression of epithelial injury markers is associated with acute lung injury severity but does not discriminate sepsis from ARDSHeatmap of correlations between the epithelial injury markers and clinical variables and laboratory exams. A – ARDS group (n = 47). B – Sepsis group (n = 30). The correlation coefficients are color-coded from deep red (− 1) to deep blue (1)Back to article page
