The Urinary Phosphate to Serum Fibroblast Growth Factor 23 Ratio, Deemed the Nephron Index, Is a Useful Clinical Index for Early Stage Chronic Kidney Disease in Patients with Type 2 Diabetes: An Observational Pilot Study

Figure 1

Comparisons of nephron index (a), daily (24 h) urinary phosphate excretion (U-P) (b), fractional excretion of phosphate (FEP) (c), serum intact FGF23 (d), estimated glomerular filtration rate (eGFR) (e), and creatinine clearance (Ccr) (f) between baseline and time after follow-up in the patients with type 2 diabetes. p < 0.05 vs. baseline, p < 0.01 vs. baseline.
