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: Metastatic melanoma to the breast is rare and may be misdiagnosed as primary breast carcinoma. Histological, immunohistochemical, and clinical correlations, such as a history of previous melanoma, are essential for diagnosis. Patient Presentation: A female patient presented with melanoma in the left gluteal region. Five years later, a palpable nodule was detected in the right breast on routine mammography. Microscopic and immunohistochemical examination confirmed the diagnosis of metastatic melanoma. The patient passed away 3 years later. Conclusion: The findings in this case indicate that metastatic melanoma can present in atypical ways and that specialists should pay attention to metastases in unusual locations in cases of melanoma.
