Serum Nitric Oxide Level Serves as a Potential Prognostic Biomarker in ACLF Patients.

Based on serum NO levels at the time of hospital admission, ACLF patients may be divided into high-risk and low-risk groups. The combination of serum NO level and MELD score is more closely linked to the patient's outcome than either value alone. This method might be used to evaluate patient prognoses and select candidates for liver transplantation.
