The expression of exosomal cirRNAs in the plasma of S-IPF patients and AE-IPF patients. A The level of exosomal cirRNAs in the plasma of stable IPF patients (S-IPF) and acute exacerbation IPF patients (AE-IPF). B Receiver operating characteristic curve of hsa_circ_0044226. C The level of exosomal cirRNAs in the plasma of IPF patients with smoking (smoking) and non-smoking (non-smoking). Each test was repeated three times. The mean differences between diagnostic groups were analyzed by Student’s t test. ***P < 0.001
