BMI: body mass index.

Factor score of each dietary pattern was classified into three groups: Low (n=50), Intermediate (n=49), and High (n=49).

^‡

Analysis of covariance was used to compare the tertile scorers for each dietary pattern, controlling for race with Tukey’s post-hoc test as adjustment for multiple comparisons. Significant mean difference between two scorer groups is represented as follows: a=Low vs. Intermediate; b=Low vs. High; c= Intermediate vs High.
