FIGURE 1.

Adjusted (LS means) mean (95% CI) treadmill duration in seconds by quartiles of the a priori diet-quality score stratified by high and low self-reported physical activity (above compared with below the median score of 294). A priori diet-quality score categories were ≤54, >54 to ≤63, >63 to ≤73, and >73. Smallest groups were the off diagonal: lowest quartile a priori diet-quality score with high activity (n = 216) and highest quartile a priori score with low activity (n = 176), whereas largest groups were subjects with the lowest quartile a priori score and low activity (n = 372) and subjects with the highest quartile a priori score and high activity (n = 350). LS, least-squares.
