Fig. 2: Heat map of the differential metabolites.
From: Metabolic changes in response to varying whole-grain wheat and rye intake
The compounds (n = 81) include eight most differential unidentified molecular features, in at least one of the six comparisons in the linear mixed model, including change in the wheat or rye interventions and difference between the wheat and rye groups after each intervention. Differences with q < 0.1 are marked with a circle. The estimate is the standardized regression coefficient from the statistical model; in the group difference comparisons, a higher estimate value represents increase of the metabolite in rye group compared to wheat. One identified metabolite (tryptophan betaine) had a significant difference between the two groups at baseline and was discarded from further analysis (data not shown).
