Limitations of the study include the cross-sectional design, which cannot establish causality, and unavailable data on types of medications used and timing of blood pressure measurements before or after dialysis.

Narsipur's editorial also urged caution in assuming that these findings simply imply that more aggressive hypertension control is needed for children with ESRD.

"First, the actual role of hypertension leading to major clinical consequences once a patient is on dialysis is distinctly unclear, particularly with age," he wrote.

In addition, there is no evidence-based consensus on the ideal level of blood pressure for either children or adults undergoing dialysis.

He argued in favor of 24-hour ambulatory measurements, which could provide better data that could be used for diagnosis and treatment as well as for predicting end-organ damage.
