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

Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine skin malignancy characterized by high recurrence and metastasis rates. Here, we present a case of primary breast skin MCC in a 65-year-old female patient who initially presented with a peanut-sized lump on her right breast, which rapidly developed into a cauliflower-like mass accompanied by intermittent pain. The patient underwent radical surgery (right mastectomy and right axillary lymph node dissection), followed by postoperative chemotherapy. Immunohistochemical examination revealed positive staining for Cytokeratin 20 (CK20), Synaptophysin (Syn), Cluster of Differentiation 56 (CD56), and Chromogranin A (CgA), confirming the diagnosis of MCC. A subsequent Positron Emission Tomography - Computed Tomography (PET-CT) scan revealed secondary liver metastasis. Despite an initial effective response to chemotherapy, the patient developed severe bone marrow suppression, necessitating a switch to maintenance therapy with capecitabine.
