CI, confidence interval; HDL, high-density lipoprotein; OR, odds ratio.

Multivariate logistic regression analysis was performed to evaluate the associations of dietary pattern with MetS and its components.

Tests for trend across quartiles were performed by using ordinal categorical variables and likelihood ratio test.
