The results of single-gene survival analysis showed that high expression of RBM11, RIC3, TRAF5, ZNF14 was associated with good prognosis of IPF, while high expression of RBM47 was associated with poor prognosis; overall survival analysis of the risk prognostic model showed that high-risk patients had poor survival, while low-risk patients had higher survival, which preliminarily indicated the correctness of the model. The gene discussed is TRAF5; the disease is idiopathic pulmonary fibrosis.
