Receiver operating characteristic curves of gastrointestinal dysfunction score, acute gastrointestinal injury, sequential organ failure assessment and Acute Physiology and Chronic Health Evaluation II in predicting 28-day mortality. A: Maximum values of gastrointestinal dysfunction score (GIDS), acute gastrointestinal injury (AGI), sequential organ failure assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE II) during the first week of intensive care unit (ICU) admission; B: Maximum combination values of GIDS or AGI with SOFA and APACHE II during the first week of ICU admission. APACHE II: Acute Physiology and Chronic Health Evaluation II; AGI: Acute gastrointestinal injury; GIDS: Gastrointestinal dysfunction score; SOFA: Sequential organ failure assessment.
