Fig 1: Discrimination and survival analyses of TTR and RBP4 levels. (A) ROC analysis of urinary TTR and RBP4 for the discrimination of ADHF by their glomerular filtration rate. (B) Kaplan–Meier curve analysis. Only the first major adverse clinical event during follow-up (28 rehospitalizations due to heart and/or kidney decompensation, 4 heart transplants, and 8 patient deaths) was considered for calculation of event-free probability.
Fig 2: Urinary levels of retinol-binding protein 4 (RBP4). (A) Urinary levels of RBP4 obtained by immunoassay (ELISA) of all ADHF patients (n = 67) at hospital admission and healthy subjects. (B) Urinary levels of RBP4 of ADHF patients with normal renal function (NRF, n = 35) and with renal dysfunction (RD, n = 32) at hospital admission. The p values in italics correspond to comparison with healthy subjects. (C) Regression line of urinary RBP4 and TTR levels of ADHF patients at hospital admission.
