CRP and rosacea: Among the biological parameters, a significant association was found between rosacea and total cholesterol (SMD = 0.40; 95% CI = −0.00, 0.81; p < 0.05), low-density lipoprotein cholesterol (SMD = 0.28; 95% CI = 0.01, 0.56; p < 0.05), and C-reactive protein (CRP) (SMD = 0.25; 95% CI = 0.10, 0.41; p < 0.05).
