Note: Unadjusted distributions of the means (SD) for continuous variables and the number of observations (%) for categorical variables are presented for the first, third, and fifth quintiles of the dietary pattern scores. A chi-square test was used for categorical variables. A nonparametric trend test (nptrend command in Stata) was used for continuous variables.
