Body mass index is inversely associated with mortality in patients with acute kidney injury undergoing continuous renal replacement therapy

Background Many epidemiologic studies have reported on the controversial concept of the obesity paradox. The presence of acute kidney injury (AKI) can accelerate energy-consuming processes, particularly in patients requiring continuous renal replacement therapy (CRRT). Thus, we aimed to investigate whether obesity can provide a survival benefit in this highly catabolic condition. Methods We conducted an observational study in 212 patients who...
