Figure 2From: Prediction of clinically relevant hyperkalemia in patients treated with peptide receptor radionuclide therapyReceiver operating characteristic curves for blood urea nitrogen and phosphate. Receiver operating characteristic (ROC) curves for (A) serum blood urea nitrogen (BUN) and (B) phosphate for the prediction of severe hyperkalemia (>6.0 mmol/l) after peptide receptor radionuclide therapy (retrospective cohort, n = 38). BUN demonstrates some value as a single, simply achievable parameter (area under the curve [AUC] = 0.75) whereas serum phosphate is not a suitable predictor (AUC = 0.37).Back to article page
