Figure 4From: KL-6 concentration in pulmonary epithelial lining fluid is a useful prognostic indicator in patients with acute respiratory distress syndromeOverall survival of ARDS patients in relation to KL-6 concentrations in ELF (a) and in serum (b). The survival rate of patients with a high KL-6 levels in ELF and serum was significantly lower than that of patients with a low KL-6 levels (ELF: p = 0.0004, serum: p = 0,0075 by log-rank test).Back to article page
