Siriopol I, et al. – This trial carried out an assessment of the fluid overload, via bioimpedance spectroscopy and serum N–terminal pro–B–type natriuretic peptide, for mortality in hemodialysis patients. The inclusion of both bioimpedance and N–terminal pro–B–type natriuretic peptide (NT–proBNP) monitoring in a more comprehensive fluid status assessment possibly led to an improvement in the diagnosis of fluid overload, with a final improvement in patients’ outcome.
