Figure 2.

Correlation among proteinuria and indexes of glomerular and tubular function in acute renal failure (ARF) period. (a, b) Significant negative relationship between proteinuria/creatininuria ratio (Pto/Cro, mg/mg) and blood creatinine clearance (BCrC, ml/min, (a)) and blood urea clearance (BUC, ml/min, (b)). (c, d) Significant positive relationship between Pto/Cro and fractional excretion of sodium (FeNa, (c)) and potassium (FeK, (d)). A statistical linear regression test analysis was performed. Data for different parameters are also shown as minimal square fitting curves.
