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

Introduction: Accessory adrenal oncocytomas are rare. Consequently, the clinical characteristics and management of this entity remain poorly defined. Case Presentation: A 65-year-old man presented with a retroperitoneal mass. Imaging revealed a 103 × 96 mm tumor adjacent to the left kidney. Hormonal evaluation indicated the tumor was nonfunctioning; however, dehydroepiandrosterone sulfate and neuron-specific enolase levels were elevated, and malignancy could not be excluded. The tumor was resected laparoscopically. Histopathological examination revealed oncocytic features, and immunohistochemistry demonstrated positivity for steroidogenic factor 1. The tumor was anatomically separate from the normal adrenal gland, supporting the diagnosis of an accessory adrenal oncocytoma. Based on the Lin-Weiss-Bisceglia criteria, the tumor was classified as borderline malignant potential. No recurrence has been observed during 2 years of follow-up. Conclusion: Accessory adrenal oncocytomas are rare entities, and their accurate diagnosis requires a comprehensive, integrated approach incorporating clinical findings, imaging studies, and detailed pathological evaluation.
