In the adjusted regression analyses, lung involvement over 50% [odds ratio (OR): 3.09 (1.03–9.28; 0.043)], C-reactive protein (CRP) > 80 ng/mL [OR: 2.97 (0.99–8.93; 0.052)], Vitamin D < 40 ng/mL [OR: 6.41 (1.21–33.88; 0.029)], and hemoglobin < 12 g/mL [OR: 3.32 (1.20–9.20; 0.020)] were independent predictors for SFR/MV, while chronic atrial fibrillation [OR: 26.72 (3.87–184.11; 0.001)], cancer history [OR:8.32 (1.28–53.91; 0.026)] and IL-6 > 40 pg/mL [OR:10.01 (1.66–60.13; 0.012)] were independent predictors of death. The gene discussed is IL6; the disease is atrial fibrillation.
