Uitdagingen bij het bepalen van de werkelijke incidentie van eindstadium nierziekte bij ouderen

Liu et al.1 provided valuable insights into the true incidence of end-stage kidney disease. However, 2 considerations could substantially impact the provided estimates of patients diagnosed with estimated glomerular filtration rate (eGFR) < 15 ml/min per 1.73 m2 who have not initiated maintenance kidney replacement therapy. First, all eGFR equations, including both Chronic Kidney Disease Epidemiology Collaboration 2009 and 2021 versions used in the analysis, mathematically heavily rely on age, reflecting the kidney function decline after the age of 40 years.
