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 .
Effects of a low-salt diet and of acute salt loading on blood pressure and intralymphocytic sodium concentration in young subjects with borderline hypertension.
1 . Three groups of young patients with borderline hypertension were studied for a 12 months period . The first was on a free sodium diet while the second was on a low-salt diet . The third group of patients underwent acute salt loading . 2 . After 12 months the group on free diet showed a significant increase of intralymphocytic sodium but no change in blood pressure was noted . Five patients who were re-checked after 24 months also had a significant increase in blood pressure . 3 . Patients treated with a low-salt diet showed a significant decrease of both intralymphocytic sodium concentration and blood pressure . 4 . After acute salt loading , borderline subjects with high intralymphocytic sodium showed a significant greater natriuresis whereas intralymphocytic sodium increased only in those subjects in whom it was initially normal
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 .
