Value of Cystatin C-Based e-GFR Measurements to Predict Long-Term Tenofovir Nephrotoxicity in Patients With Hepatitis B.

Background:Cystatin C is a genuine marker for detecting minor reductions in estimated glomerular filtration rate (e-GFR).Study Question:We aimed to investigate the efficiency of cystatin C levels in predicting nephrotoxicity due to antiviral therapy in patients with chronic hepatitis B virus infecti
