Restriction of dietary variation as observed during the intervention period. (IMAGE)
Caption
(A) Principal component analysis of weight-based, food-group-level dietary variation over the study period (Euclidean distance; n=378). Each dot represents the dietary consumption of an individual participant during a day. Ellipses represent the 95% CI of the relevant group. (B) Boxplot presenting dietary variance observed before/after (baseline and follow-up combined) and during the intervention period. Variance significantly decreased during the intervention (n=378; dispersion test on Euclidean distances at food group level). The body of the boxplot represents the first and third quartiles of the distribution, with the median line, and the whiskers extend from the quartiles to the last data point within 1.5 times IQR, with outliers beyond. *Adjusted p value<0.001. (C) Distribution of weight-based average daily consumption of food groups (n=378). CI, confidence interval; IQR, interquartile range; PCA, Principal Component Analysis.
