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

Chronic appendicitis is a common cause of recurrent right lower quadrant pain and is often difficult to diagnose because of its nonspecific presentation. Pneumatosis cystoides intestinalis (PCI), a rare condition characterized by gas-filled cysts in the intestinal wall, is usually associated with other gastrointestinal disorders. We report a 43-year-old woman with a one-year history of intermittent abdominal discomfort who was found to have chronic appendicitis with concurrent PCI, an unusual combination that created diagnostic uncertainty. Computed tomography revealed gas in the appendiceal region and adjacent bowel wall. Colonoscopy and laparoscopic appendectomy were subsequently performed, excluding other gastrointestinal lesions and confirming chronic appendicitis on histopathology. The patient recovered well after surgery, and follow-up imaging 6 months later showed complete resolution of PCI. This report contributes valuable insights into the complex relationship between chronic appendicitis and PCI. Awareness of this association may help improve diagnosis and management.
