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

The gastrointestinal tract is the most frequent extranodal site of non-Hodgkin lymphoma (NHL), accounting for up to 40% of cases. However, appendiceal lymphoma is exceptionally rare, with peritoneal involvement being even rarer. Appendiceal lymphoma often mimics acute appendicitis (AA), although it is an uncommon initial manifestation of intestinal NHL, complicating diagnosis. We report a 29-year-old male with human immunodeficiency virus (HIV) who presented with AA. An open appendectomy was planned; however, intraoperative findings- including cecal induration, ascites, peritoneal thickening, and macronodular lesions on the peritoneum and intestines-led to abandonment of the procedure. Postoperative evaluation excluded peritoneal tuberculosis (PTB), while computed tomography (CT) suggested peritoneal carcinomatosis (PC). Histopathological analysis of a parietal peritoneum specimen provided the definitive diagnosis of NHL. Appendiceal NHL should be considered in HIV-positive patients with AA. Routine histopathological evaluation and surgical intervention are essential for accurate diagnosis and effective management.
