NEUROG1 and rheumatoid arthritis: Logistic regression was used to analyze the risk factors of RA, and after adjusting for confounding factors, we found that anti-CCP positive, AKA positive, and APF positive were all independent risk factors for RA (OR = 20.24, 95% CI: 9.36–43.77, p < 0.01; OR = 4.33, 95% CI: 1.62–11.60, p < 0.01; and OR = 5.28, 95% CI: 2.33–11.99, p < 0.01) (Table 3).
