CRP and Sjogren syndrome: Multivariate logistic regression analyses identified higher c-reactive protein (OR = 1.080, 95% CI: 1.020-1.144, P = 0.008), the EULAR Sjögren’s Syndrome Disease Activity Index (OR = 1.082, 95% CI: 1.027-1.140, P = 0.003), and EULAR Sjögren’s Syndrome Patient Reported Index (OR = 1.271, 95% CI: 1.064-1.518, P = 0.008) as independent risk factors for frailty.
