Table I Demographic data of all patients used in this study

The first part shows the clinical data of patients with different diseases (see column “Group”), which represents the training set. The total number (n) of patients, gender ratio (male/female), age, serum (S) creatinine, and proteinuria status are shown. All patients included in the test set are listed in the second part. Patients representing further controls are listed in the last part of the table where blood pressure values for the hypertensive patients are given in the last column. ND, not done; DN, diabetic nephropathy; SLE, systemic lupus erythematosus; SBP, systolic blood pressure; DBP, diastolic blood pressure.
