BCHE and Abnormal renal physiology: Patients in the high CONUT score group were older, were more often female, and were more likely to have a smaller body mass index, renal dysfunction (estimated glomerular filtration [eGFR] rate <30 mL/min/1.73m2), malignancy, cognitive dysfunction, low systolic blood pressure at presentation, anemia, hyponatremia, and high CRP levels (>1.0 mg/dL), and had higher BNP levels and lower cholinesterase levels than those in the low CONUT score group (Table 1).
