PLA2R1 and deep vein thrombosis: Cox proportional hazards model showed that after adjusting for confounding factors, in addition to older age, history of deep vein thrombosis and higher urinary protein, higher baseline serum PLA2R antibody titers (odds ratio [OR], 1.034; 95% confidence interval [CI], 1.006 to 1.063; P = 0.015), and high high-sensitivity C-reactive protein level (OR, 1.049; 95% CI, 1.002 to 1.098; P = 0.041), renal pathology with segmental sclerotic lesions (OR, 3.480; 95% CI, 1.338 to 9.050; P = 0.011) were also independent risk factors for the occurrence of end point events.
