An unusual cause of back pain: a case of large nonfunctioning retroperitoneal paraganglioma presented as a large cystic lesion. A case report and review of literature.
Article in Journal of surgical case reports, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
Pheochromocytoma arising from outside the adrenal glands is also called paraganglioma. When it occurs below the diaphragm, in the organ of Zuckerkandl or retroperitoneum, it is also called extra-adrenal pheochromocytoma. Paragangliomas are rare tumors which arise from neuroendocrine cells and extra-adrenal paragangliomas (EAPs) account for only 10-15% if all paragangliomas and may present incidentally as a symptomless mass. Typical triad of sweating, headache and fluctuating hypertension if not present makes preoperative diagnosis difficult. Surgical excision is the treatment of choice. Definitive diagnosis is usually made with histological findings. We report a case of large retroperitoneal tumor with size >10 cm which was a high risk depicting malignancy.
