Diagnostic Accuracy of Urine Protein/Creatinine Ratio Is Influenced by Urine Concentration
Fig 5
Histograms of urine creatinine concentration of the 24h urine cohort (A) and the spot urine cohort (B).
Urine samples were categorized into 6 groups according to urine specific gravity. The Y-axis indicated the percentage of frequency in the particular category. The correlation between the two cohorts in each group was presented with intraclass correlation coefficients.
