In multivariate analysis, after adjusting for the factors of respiratory failure, PAH, mechanical ventilation, anti-GBM antibodies, HBG, CRP and ESRD onset to dialysis, factors including respiratory failure (OR: 11.755 [1.130–122.314]; P = 0.039) and anti-GBM antibody positivity (OR: 16.320 [1.192–223.521]) could predict death. This evidence concerns the gene CRP and respiratory failure.
