nearly significantP =0.051
Discussion In this prespecified sub-study of the WAHA trial, a diet supplemented with walnuts at ≈15% energy during 2 years resulted in a nearly significant ( P =0.051) mean 4.6 mm Hg reduction in systolic office BP and nonsignificant reductions in office diastolic BP or 24-hour ambulatory BP values compared with a control diet in fit elders (mean age 69 years), of whom 60% had mild hypertension, treated pharmacologically in most of them and well controlled in 52%.
