Data are from the 26 subjects who completed DATA and OBSERVATION in the TEST session. Values for DATA and OBSERVATION (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; ICC, intraclass correlation; OBSERVATION, direct dietary observations by dietitians.
