Table 1: Characteristics of participants in a study to determine whether pressure-mediated reflection spectroscopy (RS Score) measured by Veggie Meter can be used as a valid biomarker of fruit and vegetable (F/V) intake among African American/Black college students (Maryland, January to May 2019).
a SD=standard deviation, * statistical significance <0.05, b Pantone Skintone Guide is a visual guide to match skin tone. Lightness scale ranges from 01 - 15 where 01 represents the lightest value and 15 the darkest.
