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

Figure 1

Comparison between high serum KL-6 and low serum KL-6 patients. The enrolled patients consist of 38 (40%) patients with high serum KL-6 (idiopathic: 28 patients and secondary: 10 patients) and 57 (60%) patients with low serum KL-6 (idiopathic: 34 patients and secondary 23 patients) levels. There is no significant difference in the 6-month prognosis between the high and low serum KL-6 patients ( = 0.685) (a). In addition, high serum KL-6 patients with AEs of idiopathic or secondary ILDs and low serum KL-6 patients with AEs of idiopathic or secondary ILDs have similar 6-month outcomes ( = 0.950) (b). ILD: interstitial lung disease; KL-6: Krebs von den Lungen-6.
