Table 2 shows the differences in baseline characteristics between the UIP and NSIP patterns. Patients with the UIP pattern were more frequently male (p = 0.003) with positive ACPA titers (p = 0.020) and erosive disease (p = 0.023) than patients with NSIP. There was no difference between the groups in the remaining baseline clinical characteristics or in the treatment received. Summary statistics for all continuous variables are shown in (Supplementary Table S2). Here, PRTN3 is linked to idiopathic pulmonary fibrosis.
