*Blood pressure MESOR lowering by change in timing Diltiazem HCI (240 mg/day) assessed by self-starting CUSUM. **Standard deviation from CUSUM; if there is significant displacement of 1 SD, it would be diagnosed by a slope of 1 – 0.5 =) 0.5 SD. ***After awakening (∼08:30) or at bedtime (∼00:00).

Control chart assesses individualized anti-MESOR-hypertensive chronotherapy.* The chronobiological approach includes inferential statistical methods for the rigorous assessment of intervention effects applicable to the individual patient, eg, detecting whether the lowering in the MESOR of systolic (left) and diastolic (right) blood pressure can be associated with the time when the change in treatment timing was instituted.
