From: Serum AGE/RAGEs as potential biomarker in idiopathic pulmonary fibrosis
Serum levels and predictive capability of sRAGE for 3-year survival rates. a Results showed a significant decrease of sRAGE in IPF patients beyond 3-years. b Kaplan–Meier analysis showed IPF patients with sRAGE levels in serum under 428.25 pg/ml had lower survival rate (p = 0.014) at 3-yr follow-up. Comparison of AGEs/sRAGE levels in follow-up were analyzed by Paired sample t-test, the threshold of sRAGE levels in blood were calculated by ROC analysis and survival rate was estimated by Kaplan–Meier analysis using log-rank test as statistic contrast
