Table 1 Clinical characteristics of the group with chronic kidney disease (CKD)

From: Saliva for assessing creatinine, uric acid, and potassium in nephropathic patients

CKD stage Number of patients Number of patients by diagnosis
1 5 nephrosclerosis (n = 1), diabetic nephropathy (n = 2), polycystic kidney disease (n = 2)
2 8 nephrosclerosis NS (n = 4), diabetic nephropathy (n = 2), polycystic kidney disease (n = 2)
3 10 nephrosclerosis (n = 2), diabetic nephropathy (n = 3), polycystic kidney disease (n = 3), glomerulonephritis (n = 2)
4 5 diabetic nephropathy (n = 2), polycystic kidney disease (n = 1), glomerulonephritis (n = 1), pyelonephritis (n = 1)
5 7 diabetic nephropathy (n = 2), polycystic kidney disease (n = 2), glomerulonephritis (n = 1), unknown (n = 2)
  1. CKD stage was defined as per guidelines using estimated Glomerular Filtration Rate (eGFR) in the presence of pathologic abnormalities or markers of kidney damage [21]. eGFR thresholds for CKD stage were as follows (mL/min × 1.73 m2 of body surface area): stage 1 = eGFR equal to or greater than 90, stage 2 = eGFR 89–60, stage 3 = eGFR 59–30, stage 4 = eGFR 29–15, stage 5 = eGFR less than 15
