Annual change in eGFR between baseline and follow-up re-examination in 3193 participants of the Malmö Diet and Cancer Study-Cardiovascular Cohort according to the quartiles of suPAR concentration at baseline. The general linear model was adjusted for age, sex, baseline levels of eGFR, and follow-up time. Concentration of suPAR at baseline Q1: 0.03–2.36, Q2: 2.36–2.73, Q3: 2.73–3.26, and Q4: 3.26–15.64. eGFR, estimated glomerular filtration rate according to the Chronic Kidney Disease Epidemiology Collaboration creatinine equation23; suPAR, soluble urokinase-type plasminogen activator receptor.
