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

We report a patient with a mucocele with diffuse wall thickening diagnosed by transabdominal ultrasonography and contrast-enhanced ultrasonography. Transabdominal ultrasonography showed diffuse thickening of the entire appendix wall and an anechoic area that appeared to be fluid collected throughout the appendix lumen. However, the "onion skin sign" was not detected. Contrast-enhanced ultrasonography combined with superb microvascular imaging revealed abundant mucosal blood flow and no abnormal vascular network within the mucosa of the appendix wall. We preoperatively diagnosed a mucocele complicated by acute and chronic appendicitis, and ileocecal resection was performed. Macroscopic and microscopic findings of the resected specimens demonstrated that the appendiceal wall was diffusely thickened, with fibrosis and inflammatory cell infiltration, and that the appendiceal root rumen was narrowed with epithelial hyperplasia. No neoplastic changes were observed. The cause of the appendiceal mucocele was likely fibrosis and stenosis at the root of the appendix due to initial acute appendicitis.
