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

Renal leiomyomas are rare benign tumors that predominantly affect women in their 40s and 50s. Here, we report a case of renal leiomyoma originating from the renal sinus of a woman in her 30s. The lesion was incidentally discovered on abdominal magnetic resonance imaging as a 4 cm, well circumscribed mass with smooth margins located in the right renal sinus. Dynamic contrast-enhanced computed tomography (CT) revealed homogenous and progressive enhancement, while T2-weighted magnetic resonance imaging (MRI) demonstrated uniformly low signal. Although imaging findings suggested a renal sinus tumor, papillary renal carcinoma could not be definitively excluded by imaging. Due to the difficulty in performing computed tomography-guided biopsy, a nephrectomy was undertaken. Pathological examination confirmed the diagnosis of a renal leiomyoma originating from the renal sinus.
