Correlations with clinical outcomes. Epithelial lining fluid sPLA2 activity and correlation with PICU length of stay (A), PRISM-III₂₄ score (B), duration of mechanical ventilation (C), and oxygen therapy (D). Lines are regression lines drawn by the minimum square root method: A (y = 0.01*x +8.6); B (Y = 0.01*x +4.1); C (y = 0.01*x +3); D (y = 0.01*x +5.2). MV: mechanical ventilation; PICU: Pediatric intensive care unit; sPLA2: secretory phospholipase A2.
