Tertile 1: <16.4 μg/24-h; tertile 2: 16.4‒21.6 μg/24-h; tertile 3: >21.6 μg/24-h. In total, 229 (33%) KTR died (tertile 1: 107, tertile 2: 68, tertile 3: 54). Model 1: adjustment for age, sex and body surface area. Model 2: Model 1 + plasma albumin concentration, and protein, bread, fruit, vegetable and bread intake. Model 3: Model 1 + proteinuria, eGFR and urinary volume. Model 4: Model 1 + pre-emptive transplantation, living donor and time since transplantation. Model 5: Model 1 + calcineurin inhibitor usage, proliferation inhibitor usage and acute rejection treatment.
