Stages of CKD with details on albuminuria for stage three CKD. a. Stages of CKD. Overall 94 (27%) of participants had CKD. Stage one or two CKD (albuminuria with eGFR > 90 or between 60–90 ml/min/1.73 m²) was present in 58 (62%). Stage five CKD was present in 4 (4%). Abbreviations: CKD-Chronic kidney disease, eGFR-estimated glomerular filtration rate. b. Characterizing stage three CKD. Among participants with stage three CKD (n = 26, 28%), 6 (23%) had an isolated reduction in eGFR between 45–59 ml/min/1.73 m²; all others had either stage 3b CKD or accompanying albuminuria. Abbreviations: CKD-chronic kidney disease; eGFR-estimated glomerular filtration rate.
