Post-estimation of contrasts from linear mixed-effects regression model with random intercepts.
Covariates included in the models: age, body mass index.
Time was level 1, the individual level (Persons) were on level 2.
A two-way-interaction between group (Healthy vs. Hypertensive) and time (rest [1], AAP [2], sSRr [3], recovery [4]) was modeled using restricted maximum likelihood.
Significance level: p < 0.05.
SDNN, standard deviation of normal to normal R-R intervals; RMSSD, root mean square of successive differences; ACTH, adreno-corticotrope hormone; baPWV, brachial-ankle pulse wave velocity; cPWV, central pulse wave velocity; cPP, central pulse pressure; df, degrees of freedom.
