Management and outcome of an appendiceal collision tumour composed of neuroendocrine and mucinous neoplasms.
Article in BMJ case reports, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
We report an appendiceal collision tumour in a 23-year-old woman who presented with constipation and abdominal fullness. Imaging revealed a right lower quadrant abdominal mass that was laparoscopically resected. Histology revealed an appendiceal collision tumour composed of a low-grade mucinous neoplasm and well-differentiated neuroendocrine neoplasm. A right hemicolectomy for complete oncological control was performed revealing metastatic spread of the neuroendocrine component to the lymph nodes. No further treatment was recommended and the patient was followed with expectant management. At 2-year follow-up, no evidence of disease was found on surveillance imaging. Appendiceal collision tumours can arise in young adults; treatment should be guided by oncological principles of the component tumours.
