Figure 4From: Small airway remodeling in acute respiratory distress syndrome: a study in autopsy lung tissueProtein content in ARDS patients and controls. The graphs show collagen I, fibronectin, versican and MMP-9 content (μm2/μm) in the small airways of ARDS patients and controls. IL = inner layer, OL = outer layer. Bars represent mean; lines represent SD. *P ≤0.03 compared with controls; †P < 0.003 compared with controls.Back to article page
