From Septic Shock to Hemorrhagic Shock: A Rare Presentation of Ischemic Rectal Ulcer in a Critically Ill Patient.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Acute hemorrhagic rectal ulcer (AHRU) is an uncommon but clinically significant cause of lower gastrointestinal bleeding in critically ill patients. While stress-related mucosal disease is a well-recognized cause of upper gastrointestinal bleeding in the intensive care unit (ICU), ischemic injury involving the rectum is less frequently reported. Patients recovering from septic shock, particularly those requiring prolonged vasopressor therapy, remain at risk for delayed ischemic complications. We present a case of delayed severe lower gastrointestinal bleeding due to AHRU following septic shock, highlighting the risk of ischemic complications even after apparent clinical stabilization. A 54-year-old man with insulin-dependent type 2 diabetes mellitus presented with severe diabetic ketoacidosis and was admitted to the ICU. His course was complicated by methicillin-sensitive
