Patients with AE of IPF were classified into three groups based on the median values of standardised 3D-CT LV and CRP in each cohort: (1) patients with above the median standardised 3D-CT LV and below the median CRP, (2) patients with below the median standardised 3D-CT LV and above the median CRP, and (3) remaining patients. This evidence concerns the gene CRP and idiopathic pulmonary fibrosis.
