A Diagnostic Dilemma: High-Grade Appendiceal Mucinous Neoplasm Presenting as Acute Appendicitis in a 16-Year-Old Female - Case Report and Literature Review.
Article in Case reports in gastroenterology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: High-grade appendiceal mucinous neoplasms (HAMNs) are rare mucin-producing epithelial tumors of the appendix, typically seen in middle-aged to elderly individuals. They are defined by high-grade cytologic atypia and complex architecture but without infiltrative invasion. Occurrence in pediatric or adolescent patients is virtually unknown. Case Presentation: We report a 16-year-old female who presented with signs and symptoms suggestive of acute appendicitis. Ultrasonography supported the diagnosis. A laparoscopic appendectomy was performed. Gross examination revealed a dilated appendix with mucoid contents. Histopathological evaluation confirmed HAMN confined to the appendix. Conclusion: To our knowledge, this is the second reported case of HAMN in an adolescent. This case underscores the importance of histopathologic evaluation of all appendectomy specimens, even in young patients, due to the possibility of underlying neoplasia.
