Cumulative incidence of hospitalization due to impaired renal function (all cases, n = 207) during follow-up according to the quartiles of suPAR in 5129 participants in the Malmö Diet and Cancer Study-Cardiovascular Cohort. The Kaplan-Meier plot shows cumulative percentages of all cases of impaired kidney function (n = 207) during follow-up in quartiles: first (lowest values) to fourth (highest values) quartile of the baseline suPAR concentration. Median (range) concentrations of the quartiles 1 to 4 are shown in Table 2. The numbers at risk are shown at 5-year intervals. Cox regression adjusted for sex, fasting glucose levels, estimated glomerular filtration rate, body mass index, systolic blood pressure, smoking status (current, former, or never smokers), and use of antihypertensive treatment (yes/no) at baseline. Age was used as underlying time variable. suPAR, soluble urokinase-type plasminogen activator receptor.
