TIN: tubulo-interstitialis; eGFR 0: estimated glomerular filtration rate at the time of biopsy; eGFR 6: estimated glomerular filtration rate 6 months after biopsy; eGFR 12: estimated glomerular filtration rate 12 months after biopsy; eGFR 24: estimated glomerular filtration rate 12 months after biopsy; eGFR 24: estimated glomerular filtration rate 24 months after biopsy; eGFR 36: estimated glomerular filtration rate 36 months after biopsy.
Prt 0: proteinuria/day at the time of biopsy; prt 6: proteinura/day 6 months after biopsy; prt 12: proteinuria/day 12 months after biopsy.
