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
Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, arising from incomplete obliteration of the vitelline duct. Although often asymptomatic, it can present with life-threatening complications such as inflammation, bleeding, intestinal obstruction, and perforation. Closed-loop obstruction secondary to Meckel's diverticulum is rare, and its coexistence with acute appendicitis is exceptionally uncommon, posing a diagnostic challenge. We report the case of a 22-year-old male who presented to the emergency department with a two-day history of diffuse abdominal pain and one day of bilious vomiting. Clinical examination revealed abdominal distension, diffuse tenderness, and bowel sounds that were sluggish, suggestive of intestinal obstruction. Contrast-enhanced computed tomography (CECT) of the abdomen and pelvis demonstrated clustering of small bowel loops medial to the caecum, raising suspicion for a paracaecal internal hernia with features of closed-loop obstruction involving mid-ileal loops, though bowel wall enhancement was preserved. Exploration revealed an inflamed appendix and a gangrenous Meckel's diverticulum associated with interloop adhesions, resulting in a closed-loop obstruction of the adjacent ileal segment. Surgical management included resection of the gangrenous ileal segment along with the Meckel's diverticulum, followed by a side-to-side ileo-ileal anastomosis using a linear stapler. Appendicectomy was performed concurrently. The postoperative course was uneventful, and the patient remained asymptomatic during a six-month follow-up period. This case highlights the rare coexistence of gangrenous Meckel's diverticulum and acute appendicitis presenting as closed-loop obstruction, underscoring the importance of maintaining a high index of suspicion and a broad differential diagnosis in young patients presenting with an acute abdomen. Early surgical intervention remains crucial to prevent morbidity and ensure favourable outcomes.
