Figure 2. Percentages of low urinary creatinine excretion according to mGFR and eGFR level, by gender.

Figure shows the percentage of patients with low creatinine excretion rates according to both measured (2A) and estimated (2B) glomerular filtration rate classes in men and women. Gender-specific thresholds were defined as the 10^th percentile of the urinary creatinine distribution in patients with mGFR ≥60 mL/min/1.73 m².
