  1. Data are from the 56 subjects who completed DATA and INTERVIEW in the TEST session. Values for DATA and INTERVIEW (shown as mean ± SD) are untransformed data. Paired comparisons and ICC analyses were conducted on transformed (natural log) data. Asterisks indicate where the mean differences are statistically significant. ICC p-values are listed as 0.000 because they are all less than 0.0005. DATA, Dietary Analysis Tool for Athletes; INTERVIEW, 24-h dietary recall interview using the USDA 5-step multiple-pass method; ICC, intraclass correlation.
