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

Introduction: Angiomyolipoma (AML) is a mesenchymal tumor composed of blood vessels, smooth muscle, and adipose tissue, and is generally considered benign. However, epithelioid angiomyolipoma (eAML) is a rare and aggressive variant with metastatic potential. Molecular characterization utilizing the tuberous sclerosis complex (TSC)-mTOR pathway is beneficial in advanced disease. This report describes the clinical course, histopathological findings, and molecular analysis of a patient with metastatic eAML. Methods: A 59-year-old Japanese man with no personal or family history of tuberous sclerosis (TSC) was admitted to the hospital with gradually worsening back pain and initially diagnosed with clear cell renal cell carcinoma (ccRCC). He underwent nephrectomy, followed by hepatic recurrence treated with pazopanib and subsequent axitinib. Both were discontinued due to intolerance, and the two remaining liver metastases were surgically resected. Histopathological examination of the resected lesions revealed eAML. After several recurrences and resections, unresectable hepatic and pulmonary metastases eventually developed. Results: Comprehensive genomic profiling (CGP) using the resected liver metastasis specimen identified two somatic Discussion: This case suggests that CGP can help identify actionable alterations in eAML, such as
