Figure 1 Receiver operator characteristic curves (ROC) for gradient boosting models predicting the risk of future hyponatremia using baseline participant characteristics: the red curve describes the full model, the black curve describes a model that was trained without some variables from the lipid profile (high-density lipoprotein, total cholesterol, and triglycerides). The vertical lines give the false positive rate for the predetermined sensitivity of 50%. AUC = area under the curve.

Figure 2 Density plots comparing high-density lipoprotein cholesterol (HDL-C) at baseline in Systolic Blood Pressure Intervention Trial (SPRINT) participants who developed hyponatremia (red) during the study and patients who did not develop hyponatremia (blue). Baseline HDL-C was significantly more elevated in participants who later developed hyponatremia, for both males and females (P <.0001 in both sexes; Wilcoxon test).
