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

Appendiceal neoplasms (ANs) are rare and often mimic acute appendicitis, complicating timely diagnosis. We report a unique case of a 57-year-old male presenting with right lower quadrant pain, found on imaging to have a ruptured appendiceal mucocele. He underwent open right hemicolectomy, and histopathology revealed concurrent moderately differentiated mucinous adenocarcinoma arising within a high-grade appendiceal mucinous neoplasm-the first such case documented in the literature. This case underscores the need for early detection, proper surgery, and long-term follow-up in managing rare concurrent appendiceal tumors.
