The Kidney Failure Risk Equation (KFRE) Calculator is a vital tool for predicting the risk of progression to kidney failure in patients with chronic kidney disease (CKD). By utilizing key clinical variables, this calculator helps healthcare providers make informed decisions about patient management and treatment strategies.
The KFRE Calculator provides a standardized approach to assess disease progression risk in CKD patients, enabling evidence-based clinical decision-making.
