PRTN3 and sensorineural hearing loss disorder: We identified independent factors associated with GPA-related HCP using binary logistic regression analysis (Table 3), which included PR3-ANCA negativity (odds ratio [OR] 10.698, 95% confidence interval [CI] 2.547–44.923, p = 0.001), conductive or sensorineural hearing loss (OR 10.855, 95% CI 2.018–58.389, p = 0.005), and decreased vision or sudden visual loss (OR 8.647, 95% CI 1.519–49.241, p = 0.015).
