Table 3: The predictive value of using 24h CASP to diagnose non-dipping with 24h brachial dipping as reference in hypertensive patients and healthy controls.

Predictive Value of Non-Dipping

10% nocturnal CASP decrease |
17% |
38% |
5% nocturnal CASP decrease |
14% |
25% |
Abbreviation: CASP: Central Aortic Systolic Pressure.
Calculations: Predictive value of non-dipping = (CASP and brachial non-dippers)/(all CASP non-dippers)*100.
