However, no significant differences were observed when TWEAK levels were compared in patients with PM/DM sub-grouped based on ANA positivity (Figure 1C), Jo-1 positivity (Figure 1D), presence of interstitial lung disease (ILD) (Figure 1E) and presence of oropharyngeal dysphagia (Figure 1F). This evidence concerns the gene BTG3 and interstitial lung disease.
