TRAF5 and idiopathic pulmonary fibrosis: We construct a riskscore model as an indicator to predict the prognosis of IPF [riskscore = (−0.44084*RBM11) + (0.631579*RBM47) + (−0.01935*RIC3) + (−0.58291*TRAF5) + (−0.00528*ZNF14)], and then survival analysis was performed to assess the effect of the above genes on the prognosis of IPF patients.
