Statistical methods
Statistical analyses were conducted with the statistical
package SPSS 14. for Windows. Wilcoxon’ssigned ranks test was used to estimate the differences
between the paired observations of blood
pressure and BF. Between groups comparisons of
systolic (SBP) and diastolic blood pressure (DBP)
were made using Wald–Wolfowitz runs test. This
is a non-parametric test that checks the randomness
hypothesis of a data sequence [19]. A p-value
< 0.05 was considered significant.
