Fig. 4: Best and worst day combinations at different minimum days for reliable dietary assessment of different nutrients/food groups.
From: Minimum days estimation for reliable dietary intake information: findings from a digital cohort
For each nutrient and at each number of days, the day combinations which yielded the highest (in color) and lowest ICC scores (in gray) are shown. The plot is ranged between ICC values of 0.75–1.0, with the ICC reliability threshold at 0.9 shown as a red line - points lying below this range are not shown.
