For most comparisons , the credibility of evidence was rated very low to moderate , with the exception for the DASH vs. the low-fat dietary approach for which the quality of evidence was rated high .
Conclusion : The present network meta- analysis suggests that the DASH dietary approach might be the most effective dietary measure to reduce blood pressure among hypertensive and pre-hypertensive patients based on high quality evidence
ABSTRACT Background : Pairwise meta-analyses have shown beneficial effects of individual dietary approaches on blood pressure but their comparative effects have not been established .
Objective : Therefore we performed a systematic review of different dietary intervention trials and estimated the aggregate blood pressure effects through network meta- analysis including hypertensive and pre-hypertensive patients .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
