FIGURE 4.

Bland–Altman plots (A–H) of included food timing parameters. The mean difference (middle horizontal line) represents the estimated concordance, and the SD of the differences (upper and lower horizontal lines) measures the random fluctuations around the mean. The timings for the first and last eating occasions and midpoint of intake were averaged from multiple days of food records on workdays and free days separately, whereas the timing of the main eating occasion was designated as the median time. For food records, the main eating occasion was based on the largest percentage calories of the day. For both recall and food records, the midpoint of intake was calculated as the midway clock time between first and last eating occasions.
