The number of people older than 65 years with diabetes was 135.6 million in 2019, and will reach 276.2 million by 2045 [1]. Additionally, the estimated prevalence of diabetes in adults today has reached 537 million (10.5% of the global population in 2021) [2]. Population aging and increasing prevalence of diabetes are two important factors associated with an increasing incidence of chronic kidney disease (CKD). An accurate estimation of glomerular filtration rate (GFR) can help with the identification and management of CKD.
