CRP and systemic sclerosis: In the SSc patients, low-density lipoprotein cholesterol (LDL-C) (OR = 3.212, 95%CI = 1.132-9.113, p= 0.028), ESR (OR = 1.218, 95%CI = 1.086-1.367, p= 0.001), CRP (OR = 2.156, 95% CI = 1.393-3.338, p = 0.001), T helper (Th)cells (OR = 1.004, 95% CI = 1.001-1.008, p = 0.034) were positively correlated with the risk of SSc.
