Daily potassium intake and sodium-to-potassium ratio in the reduction of blood pressure: a meta-analysis of randomized controlled trials July 2015
Why eat three bananas a day? April 2012This one is even more worthless, NO protocol, NO amounts and types of food to get to the dose suggested.
- In this study researchers looked into the observational cohort studies tending to the connection between potassium consumption, and incidence or mortality of total stroke or stroke subtypes published through August 6, 2016.
- They carried out a meta–analysis of 16 cohort concentrates on in view of the relative risk (RR) of stroke comparing the highest versus lowest consumption categories.
- They additionally plotted a pooled dose–response curve of RR of stroke according to potassium consumption.
- Investigations were performed with and without adjustment for blood pressure.
- Relative to the lowest category of potassium consumption, the highest category of potassium consumption was connected with a 13% diminished risk of stroke (RR=0.87, 95% CI 0.80–0.94) in the blood pressure–adjusted examination.
- Summary RRs tended to diminishing when original estimates were unadjusted for blood pressure.
- Examination for stroke subtypes yielded comparable results.
- In the spline examination, the pooled RR was lowest at 90 mmol of potassium daily consumption (RRs=0.78, 95% CI 0.70–0.86) in blood pressure–adjusted investigation, and 0.67 (95% CI 0.57–0.78) in unadjusted examination.
