Ambulatory Blood Pressure Thresholds and Left Ventricular Hypertrophy in Children Aged 6-12 Years: A Pediatric Nephrology Research Consortium Study.

Among 279 children, hypertension was present in 51% and left ventricular hypertrophy in approximately 20%.

Across all systolic and diastolic ambulatory blood pressure monitoring thresholds tested, area under the receiver operating characteristic values ranged from 0.5 to 0.6, indicating poor discriminatory performance, including analyses restricted to children without chronic kidney disease or obesity.
