Effectiveness of interventions to reduce trans-fatty acid intake in the systematic review of dietary reduction policies

TFA: trans-fatty acid.

Notes: Plot of the reported reductions in TFA consumption (g/day) of the 12 empirical studies included in this systematic review, by type of intervention. An unweighted median regression model was fitted to the data and is depicted by the grey line on the plot. We used the National Heart, Lung and Blood Institute quality assessment tools to assess the quality of empirical studies.¹⁷
