Conversely, elevation in CEACAM1 (OR: 0.3957, 95% CI: 0.1687-0.9283, PIVW: 0.0331), MMP-1 (OR: 0.6170, 95% CI: 0.4300-0.8852, PIVW: 0.0087), NT-proBNP (OR: 0.7225, 95% CI: 0.5416-0.9639, PIVW: 0.0271), VEGFR-3 (OR: 0.6532, 95% CI: 0.4607-0.9263, PIVW: 0.0169), and angiogenin (OR: 0.0960, 95% CI: 0.0212-0.4358, PIVW: 0.0024) was associated with a decreased risk of giant cell arteritis. This evidence concerns the gene MMP1 and arteritis.
