CRP and metabolic syndrome: When the data were stratified based on whether the participants had MetS, compared with T1, both the 2nd and 3rd tertiles of the DII had a higher CRP level (β-Coefficients T2 versus T1 = 0.086, 95% CI: 0.004–0.167; β-Coefficients T3 versus T1 = 0.145, 95% CI: 0.045–0.245) among subjects with MetS.
