Implication
Absolute BP variability differences should not guide hypertension management; leaves open central modulation of relative variability for prospective study.

Outcome
Blood pressure and heart rate variabilities (long- and short-term) assessed via 24-hour intra-arterial recordingsurrogate
Absolute blood pressure variability is greater in hypertensive patients compared to normotensives, but relative variability and heart rate variability remain similar, suggesting central nervous mechanisms play a primary role in cardiovascular modulation regardless of baseline blood pressure.
