Estimation of GFR in Patients With Cystic Fibrosis: A Cross-Sectional Study

Patients with cystic fibrosis (CF) have frequent infectious complications requiring nephrotoxic medications, necessitating monitoring of renal function. Although adult studies have suggested that cystatin C (CysC)-based estimated glomerular filtration rate (eGFR) may be preferable due to reduced muscle mass of patients with CF, pediatric patients remain understudied.Our objective was to determine which eGFR formula is best for estimating...
