Figure 3. GAG shedding predicts ARDS severity and duration.

(A) Assessment of the relationship between GAG shedding and P_aO₂:F_iO₂. n = 25 patients with ARDS in whom arterial blood gas data were available. (B–D) Assessment of the relationship between GAG shedding and duration of mechanical ventilation (B), ICU length of stay (C), and hospital length of stay (D) in patients with ARDS. n = 64 patients with ARDS in whom full data regarding duration of critical illness were available. Spearman ρ and P values were computed as indicated on each graph.
