Summary of the results reported by a meta-analysis of randomized controlled trials in adults according to dietary interventions. Green: evidence of a beneficial effect (i.e., a decrease in all outcomes except HDL-C); grey: no effect; red: evidence of a detrimental effect (i.e., an increase in all outcomes except HDL-C). The size of the circles reflects the number of unique meta-analyses available. BMI, body mass index; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; TG, triglycerides; HbA1c, glycated hemoglobin; BP, blood pressure; GI, glycemic index; GL, glycemic load; ER, energy restriction; DASH, Dietary Approaches to Stop Hypertension.
