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

Background: Tuberous sclerosis complex (TSC) is frequently complicated by renal lesions, including angiomyolipoma (AML), renal cysts, and renal cell carcinoma (RCC). Large deletions involving adjacent Case presentation: A 13-year-old boy with hypomelanotic macules and facial angiofibromas presented with acute abdominal pain and fever; CT revealed a ruptured heterogeneous 5-cm right renal cystic, and multiple cysts. Robot-assisted partial nephrectomy confirmed epithelioid angiomyolipoma (eAML) via pathology and immunohistochemistry (cathepsin K+, CD10/p53 partial+, others negative). Neuroimaging and ophthalmology revealed TSC features; chromosomal microarray identified an ∼882-kb 16p13.3 deletion encompassing Conclusions: PKDTS may manifest in childhood as an eAML rupture. In pediatric TSC, eAML or RCC should not be excluded based on age. Atypical findings (e.g., calcification or necrosis) warrant early biopsy; non-diagnostic sequencing requires copy-number analysis (e.g., chromosomal microarray) to detect
