The eGFR is a critical measure in public health epidemiology for several reasons:
1. Early Detection: It helps in the early detection of CKD, which is often asymptomatic in the initial stages. 2. Prevalence Studies: It aids in understanding the prevalence and incidence of CKD in different populations. 3. Risk Stratification: It assists in stratifying individuals based on their renal function, allowing for better management of risk factors. 4. Public Health Interventions: It informs public health policies and interventions aimed at reducing the burden of CKD.
