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

introductionOccult breast cancer (OBC) is defined as metastatic breast carcinoma without detectable breast lesions on clinical or imaging evaluation. Most cases are diagnosed from axillary lymph node metastasis (ALNM), while presentation from other sites is rare. CASE PRESENTATION: A 49-year-old woman with prior gastric cancer developed a 20-mm scalp mass, which was surgically excised. Pathology and immunohistochemistry confirmed metastatic breast carcinoma (hormone receptor-positive and HER2-negative). No breast or axillary lesions were detected by imaging, including PET-CT scan. She was diagnosed with OBC without ALNM and started endocrine therapy with anastrozole.

conclusionsWe report a rare case of OBC diagnosed based on a solitary scalp metastasis without ALNM. OBC without ALNM appears to favor luminal type and distinct metastatic sites, but further cases are needed to establish treatment strategies.
