Serum levels of esRAGE in patients with IPF and control subjects
The serum levels of endogenous secretory receptor for advanced glycation end products (esRAGE) in patients with idiopathic pulmonary fibrosis (IPF) were significantly lower than those in controls (162.0 ± 102.4 ng/ml and 200.7 ± 107.3 ng/ml, p = 0.009, respectively). Key: boxes represent the 25th to 75th percentiles; solid lines within the boxes show the median values; whiskers are the 10th and 90th percentiles; and the small circles represent outliers *p < 0.05 (Mann-Whitney U-test) SD, standard deviation
