Harvest plots presenting direction of effect for subgroups of all studies, showing acute effects (A) at rest and (B) on vasodilator responses, and chronic effects (C) at rest, and (D) on vasodilator responses. The colours of the bars represent the microvascular bed studied. Tallest bars= ‘low risk of bias’, shortest bars= ‘high risk of bias’. ‘1’ represents a positive effect of cocoa flavanols (CFs), and ‘0’ represents increased outcomes with placebo vs. CFs
