Figure 2 Receiver operating characteristic (ROC) curve of hemodialysis (HD)-unit blood pressures and the presence or absence of hypertension as defined by ambulatory blood pressure monitoring. (A) Systolic blood pressure (BP); (B) diastolic BP. Symbols are: (▴) pre-HD; (▪) post-HD. The diagonal straight line at 45° indicates a hypothetical test with no predictive value. The area under the curve (AUC) for each of the curves was at least 80%. Sensitivities and specificities for each BP value and the AUCs are shown in Table 3.

Figure 3 Bland-Altman plots for HD unit BPs and ambulatory BPs. The horizontal line is the average difference between the two tests and the dotted line is ±2 SD of the difference (agreement limits). There was poor agreement between the two tests. Kidney International 2001 60, 1982-1989DOI: (10.1046/j.1523-1755.2001.00997.x) Copyright © 2001 International Society of Nephrology Terms and Conditions
