The clinical variables associated with metabolism, including TG, Apo AI, and AIB were significantly lower (p = 0.008, p = 0.023, and p < 0.001, respectively) and GLU was significantly higher in the AE-IPF group than those in the S-IPF group (p < 0.001). Here, APOA1 is linked to idiopathic pulmonary fibrosis.
