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.
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
objectivesTo investigate the incidence and nature of unusual histopathological findings in appendectomy specimens and assess their impact on post-appendectomy management.
methodsA retrospective study was conducted on patients who underwent appendectomies at Jordan University Hospital between January 2015 and December 2024. It included patients with presumed diagnoses of acute appendicitis or those who underwent incidental appendectomies during other surgical procedures. Pathology reports with complete data and slides showing unusual findings were retrieved from the archives of the histopathology laboratory of the hospital. Statistical Package for the Social Sciences was used for statistical analysis.
resultsOf the 2,275 patients, unusual histopathological findings were identified in 171 (7.5%). These findings included fibrous obliteration (2%), serositis (1.2%), fecalith impaction (1.1%), low-grade appendiceal mucinous neoplasms (1%), mucinous adenocarcinoma (0.4%), Enterobius vermicularis infection (0.4%), well-differentiated neuroendocrine tumors (0.3%), mucosal hyperplasia (0.3%), endometriosis (0.3%), colon carcinomas involving the appendix (0.2%), high-grade appendiceal mucinous neoplasms (0.1%), diverticulosis (0.1%), ischemic changes (0.1%) and a sessile serrated polyp (0.0%).
conclusionAlthough acute appendicitis remained the primary diagnosis, appendectomy specimens revealed various incidental pathologies. Notably, mucinous neoplasms were more frequent than well-differentiated neuroendocrine tumors.
