1 · What the graph read from it

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.

2 · The registry

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

Left paraduodenal hernias, an abnormal protrusion of abdominal organs through a peritoneal defect into the fossa of Landzert, are a rare cause of small bowel obstruction. We present the case of a 21-year-old man with intermittent abdominal pain over several months. Diagnostic laparoscopy confirmed a left paraduodenal hernia. The hernia was reduced, and the fossa of Landzert was left widely open. This condition presents a diagnostic challenge, as symptoms are non-specific and imaging may appear unremarkable. Prompt diagnosis is essential to avoid complications such as strangulation and ischemia. Unlike conventional approaches, our surgical strategy involved enlarging and intentionally leaving the hernial defect open-justified by anatomical and pathophysiological reasoning. At 21-month follow-up, the patient remained symptom-free. This case highlights the importance of maintaining a high index of suspicion in similar clinical presentations and proposes an alternative surgical technique for managing this rare internal hernia.
