Fig. 3From: Exosomal circRNAs in the plasma serve as novel biomarkers for IPF diagnosis and progression predictionThe expression level of exosomal hsa_circ_0044226 (A), hsa_circ_0004099 (B), hsa_circ_0008898 (C) in IPF patients and control volunteers by RT-qPCR. IPF IPF patients, non-IPF control volunteers. Each test was repeated three times. The mean differences between diagnostic groups were analyzed by Student’s t test. ***P < 0.001Back to article page
