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

backgroundsEwing Sarcoma (ES) is an aggressive pediatric bone tumor requiring multimodal treatment. Primary renal ES is extremely rare and often presents with nonspecific symptoms, potentially delaying diagnosis. Imaging aids detection, while histopathological and molecular analyses confirm the diagnosis. CASE DESCRIPTION: We report on a 31-year-old female who was initially treated for pyelonephritis. As computerized tomography suggested a malignant kidney tumor with an extensive inferior vena cava thrombus, nephrectomy and caval ligation were performed. Histopathology and further staging confirmed primary renal ES, which was subsequently treated with adjuvant polychemotherapy.

conclusionsThe present case highlights the variable clinical spectrum of malignant kidney tumors. ES should be considered in the differential diagnosis of atypical renal masses.
