2.5.7. Statistical Analysis
SECONDARY, REGRESSIONS
Statistical analysis was performed as per protocol. Primary and secondary parameters were measured at baseline and after 12 weeks of intervention. Data are presented as mean ± standard deviation of the mean. Two-way ANOVA and multiple comparisons, used to analyze the treatment effect, were performed using Sidak’s test. A statistical analysis of initial differences between Groups A and L was performed by a two-tailed unpaired Student’s t-test. A Chi-square test was performed for categorical variables. Correlation analysis between the change in blood pressure and confounding variables was performed by Pearson’s correlation analysis. To determine the evolution in home blood pressure measurements, linear regressions were conducted between the days of treatment (0–84 days) and the mean of the blood pressure taken daily. Differences in slopes were monitored by a two-tailed t-test analysis. In all cases, the cut-off to determine significant differences between groups was set at a
