sPLA2 and molecules related to its activity or expression in epithelial lining fluids. Pooled data from cases and controls. TNFα (Panel A; *P = 0.04), sPLA2 total activity (Panel B; §P = 0.01), FFA (Panel C; #P = 0.026) and total phospholipids (Panel D; ♥P = 0.0001) are significantly different between ARDS and controls. Panel E shows sPLA2/SP-A ratio and Panel F shows results presented in the other panels, normalized as unit-free ARDS patients/controls ratio. Data are shown as medians or mean, as appropriate; T-bars represent standard error. ARDS: acute respiratory distress syndrome; FFA: free fatty acids; SP-A: Surfactant protein A; sPLA2: secretory phospholipase A2; TNFα: tumor necrosis factor-α.
