Anti‐OJ ASS was associated with a higher inflammatory score, endomysial and perimysial CD68 infiltration scores, perivascular inflammatory cell infiltration score, and a higher prevalence of perivascular inflammatory cell infiltration and vasculitis (6.8 ± 3.2 vs. non‐OJ ASS 4.5 ± 2.9, p = 0.006; 1.9 ± 0.4 vs.1.6 ± 0.6, p = 0.02; 1.6 ± 0.7 vs. 1.0 ± 0.8, p = 0.0007; 0.8 ± 0.4 vs. 0.4 ± 0.5, p = 0.002; 75.0% vs. 36.5%, p = 0.002; 45.0% vs. 11.2%, p = 0.0009, respectively) (Figure 3B, eTables S3, S5 and S6). Here, CD68 is linked to vasculitis.
