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 sinus schwannomas are extremely rare. In this study, we inform a case of a large schwannoma that was suspected to have originated in the renal sinus based on preoperative imaging. A male in his 40s was referred to our hospital due to the incidental detection of a large tumor in his right kidney was during an abdominal CT scan performed to discover the underlying cause of decreased renal function. The tumor was a well-circumscribed mass, 17 cm in diameter, and contained large cystic degeneration. The contrast-enhanced CT revealed that the tumor was pressing on the normal structures of the renal parenchyma, renal pelvis, and renal artery. MRI was taken. The solid part of the tumor showed a uniform slightly high signal on T2-weighted image. Consequently, nephrectomy was performed. On pathological examination, the tumor was schwannoma originated in the renal sinus. If a huge well-circumscribed tumor is found in the renal sinus, a schwannoma should be listed in the differential.
