P < 0.05 was considered statistically significant. M-Ammonia: Mean-level of ammonia; I-Ammonia: Initial-level of ammonia; ICU: Intensive care unit; APACHE-II: Acute Physiologic Assessment and Chronic Health Evaluation II; H-SOFA: The high level of Sequential Organ Failure Assessment score; L-GCS: The low level of Glasgow Coma Scale score; M-SOFA: The mean level of Sequential Organ Failure Assessment score; M-GCS: The mean level of Glasgow Coma Scale score; I-SOFA: The initial level of Sequential Organ Failure Assessment score; I-GCS: The initial level of Glasgow Coma Scale score.
