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

Perirenal hemangiomas are rare benign vascular tumors that can present as indeterminate retroperitoneal masses and mimic renal, adrenal, or soft-tissue malignancy. We report the case of a 60-year-old woman who was incidentally found to have a right perirenal mass adjacent to the kidney and adrenal gland. Due to concern for a possible sarcoma, core biopsy was performed and demonstrated a benign vascular neoplasm compatible with hemangioma. This case highlights the diagnostic challenge of rare perirenal hemangiomas and the importance of considering vascular lesions when planning biopsy of enhancing retroperitoneal masses.
