Nasopharyngeal carcinoma metastasis to the breast.
Review in Saudi medical journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Breast metastases from extra-mammary neoplasms are rare, accounting for less than 2% of breast cancer cases. A 43-year-old female patient presented with a mass in her left breast and swelling in her left axillary region. A histopathological examination of the mass showed enlarged polygonal tumor cells with scant to moderate, eosinophilic to amphophilic cytoplasm and enlarged, hyperchromatic and pleomorphic nuclei with irregular nuclear membranes. An immunohistochemistry (IHC) examination was positive for pan cytokeratin and negative for CK7, CK20, S-100, LCA, HMB45, CD 20, desmin, myogenin, GCFDP-15, transcription factor-1, villin, estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. As she was a known case of nasopharyngeal carcinoma, and based on the histopathology ndings and IHC profile, the patient was diagnosed with breast metastasis from NPC. The patient was deceased 3 months after refusing the recommended medical intervention.
