Table 1 Statistical analysis of hemodynamic parameters at baseline and 1st minute post-CPT.
| Baseline | CPT-1 | P values | |
|---|---|---|---|
| Systolic blood pressure (mmHg) | 120.6±10.93 | 131.5±10.47 | * |
| Diastolic blood pressure (mmHg) | 74.65±7.66 | 80.7±7.22 | # |
| 76 (59–85) | 81 (63–92) | ||
| Pulse rate (beat/min) | 76.03±7.97 | 85.5±8.57 | * |
| Velocity (cm/sec) | 43.14±18.73 | 53.7±23.77 | * |
| Diameter (mm) | 7.76±2.89 | 6.97±2.51 | * |
| Flow rate (ml/min) | 379.3±253.5 | 518.5±285.6 | * |
| * Paired test with mean±standard deviation (SD); # Wilcoxon signed-rank test with mean±SD and median (min-max). CPT – cold pressor test; CPT-1 – 1-minute measurement after the CPT. | |||
