Diagnostic Accuracy of Urine Protein/Creatinine Ratio Is Influenced by Urine Concentration
Fig 2
Association of urine specific gravity and the percentage discrepancy between urine protein/creatinine ratio (UPCR) and 24-hour urine protein excretion (24h-UP).
for dilute urine, UPCR overestimates 24h-UP. As the urine specific gravity increases, UPCR underestimates 24h-UP. Dot: mean; bar: 95% confidence interval.
