Variables are presented as mean (standard deviation)
AHEI Alternate Healthy Eating Index, BMI Body mass index
1P value of the Student’s t-test for the difference between participants classified true positive (AHEI< 65 and classification as low diet quality with the Brief Diet Quality Assessment Tool) and false negative (AHEI< 65 and classification as high diet quality with the Brief Diet Quality Assessment Tool)
aThis analysis included only individuals from the predictive validation sample among whom the AHEI was < 65 (total N = 592)
