In the highest quartile of CRP levels (>1.50 mg/L), the risk for MetS was substantially higher (0R 5.97; 95 % CI 4.75–7.51) compared with that in the lowest quartile of CRP levels (≤0.33 mg/L) after adjustment for age, sex, geographic location, lifestyle factors, level of education attained, and family history of chronic diseases [19]. Here, CRP is linked to metabolic syndrome.
