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

Abdominal contrast-enhanced computed tomography (portal venous phase, thin-slice reconstruction) demonstrated a distended appendix measuring 10 mm in diameter with peri-appendiceal fat stranding, without visible appendicolith, focal outpouching, or mural defect, suggesting uncomplicated acute appendicitis. Appendiceal diverticula were not identified preoperatively. The patient underwent laparoscopic appendectomy. Intraoperatively, multiple inflamed diverticula were observed. Histopathological examination confirmed appendiceal diverticulitis with peridiverticulitis, without evidence of neoplasm. The postoperative course was uneventful. This case highlights the difficulty of preoperative diagnosis and the limitations of CT in detecting appendiceal diverticula.
