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

Amyand's hernia, defined as the presence of the vermiform appendix within an inguinal hernia sac, is an uncommon surgical finding. The association with appendiceal neoplasms is exceedingly rare, particularly in the absence of inflammatory signs. We report the case of a 71-year-old male with a longstanding right inguinoscrotal hernia presenting with progressive discomfort. An open hernia repair revealed the cecum and a macroscopically non-inflamed appendix within the hernia sac. Appendectomy was performed, followed by sutureless mesh hernioplasty. Histopathological examination unexpectedly demonstrated a low-grade appendiceal mucinous neoplasm with free resection margins. The postoperative course was uneventful, the patient remained asymptomatic at follow-up. This case suggests that even a clinically silent appendix within an Amyand's hernia may harbor occult neoplastic pathology. Appendectomy should therefore be considered in adult patients to avoid missed diagnoses with potential oncological implications.
