BP-lowering effect of the DASH diet in adults with and without hypertension: total analysis for SBP and DBP outcomes and sensitivity analyses, according to clinical and methodological characteristics of the selected trials. Difference in means of attained SBP and DBP difference in trials investigating the effect of the DASH diet compared with a control diet. From left to right, the columns indicate the type of analysis, the number of trials analyzed, the number of subjects per randomized arm in each separate analysis for both BP outcomes, the heterogeneity in each analysis for each outcome, the difference in means and 95% CIs for each outcome under the appropriate model based on heterogeneity (the minus sign indicates a lower BP value in the first group), and the forest plots of the difference in means and 95% CIs (black = SBP reduction and gray = DBP reduction). BP, blood pressure; DASH, Dietary Approaches to Stop Hypertension; DBP, diastolic blood pressure; ITT, intention-to-treat; RCT, randomized controlled trial; SBP, systolic blood pressure.
