No significant effect on any cardiometabolic outcome overall. Subgroups suggested lower total and LDL cholesterol when baseline cholesterol was under 200 mg/dL and lower systolic pressure with more than 50 mg/day anthocyanins, while fasting glucose rose in people aged 50 or younger. Certainty of evidence was very low.
