Comparison of Clinical Features between the High and Low Serum KL-6 Patients with Acute Exacerbation of Interstitial Lung Diseases

Figure 4

Incidence of complications according to serum KL-6 levels and 6-month outcomes. From the left bar, there are four groups, including survivors with low serum KL-6 (A), nonsurvivors with low serum KL-6 (B), survivors with high serum KL-6 (C), and nonsurvivors with high serum KL-6 (D) levels. The incidences of congestive heart failure, symptomatic chronic pulmonary disease, cerebrovascular disease, and second metastatic solid tumours are significantly the highest in nonsurvivors with low serum KL-6 levels (all  < 0.05). KL-6: Krebs von den Lungen-6.
