Table 4 Variance analysis comparison (T1 vs. T3) of the 2 preeclampsia groups.
| Control group (n = 15) | Intervention group (n = 14) | Variance analysis p (η p 2 )/observed power | |||||||
|---|---|---|---|---|---|---|---|---|---|
| T1° | T3° | d | T1° | T3° | d | Group | Time | Group × time | |
| The data are given as ° mean ± standard deviation and significant differences are shown in bold. d = effect size; significance level: p < 0.05 and η p 2 ≥ 0.10, d ≥ 0.50 and observed power ≥ 0.80 AIx: augmentation index; AoPP: aortic pulse pressure; CO: cardiac output; MAP: mean arterial pressure; T: measurement time; BP: blood pressure; SEVR: subendocardial viability ratio; SV: stroke volume | |||||||||
