Parathyroid hormone and vitamin D modulate nocturnal blood pressure dipping: a retrospective cohort study in primary hypertension

Calcium-phosphate dysregulation (elevated PTH, low vitamin D) independently contributes to non-dipping, suggesting biomarker-guided approaches for circadian BP control. Demographic disparities in dipping may reflect underlying mineral metabolism disturbances. Prospective trials should explore calcium-modulating therapies (e.g. vitamin D supplementation) in non-dipper hypertension.
