Relative expression (qRT-PCR) of the five lncRNAs and one mRNA in SSc patients (30 patients with SSc-ILD, 30 patients with SSc-NILD) and RA patients (30 patients with RA-ILD, 30 patients with RA-NILD). SSc, systemic sclerosis; RA, rheumatoid arthritis; ILD, interstitial lung disease; NILD, without interstitial lung disease. P < 0.05 was considered to indicate statistical significance.
