Receiver-operating characteristic (ROC) curves for diagnosing left ventricular hypertrophy
| Area under systolic ROC curve |

|---|---|---|
| full data (95% CI)a | random matched data (95% CI)a | |
| Routine dialysis unit blood pressure | ||
| Pre-HD | 0.63 (0.53–0.74) | 0.63 (0.52–0.73) |
| Post-HD | 0.61 (0.51–0.71) | 0.61 (0.50–0.71) |

| Pre-HD | 0.64 (0.53–0.74) | 0.65 (0.54–0.75) |
| Post-HD | 0.60 (0.49–0.70) | 0.57 (0.47–0.68) |
| Home blood pressure | 0.69 (0.60–0.79) | 0.71 (0.61–0.80) |
| 44-hour ambulatory BP | 0.64 (0.54–0.74) | 0.62 (0.53–0.72) |

All areas under the ROC curve were significant except post-dialysis standardized at p < 0.05. The home systolic blood pressure area under the ROC curve was significant at p < 0.0001.
