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

Malignant melanoma (MM) is difficult to diagnose because of its pleomorphic morphology and diverse protein profile. We describe a case of canine oral MM that exhibited rhabdoid cell differentiation. The tumor contained two cell types: typical MM cells and aggregated rhabdoid cells. Immunohistochemically, both types of neoplastic cells were positive for vimentin and desmin. Typical MM cells are positive for melanocytic markers; a subset of rhabdoid cells is negative for melanocytic markers and positive for myogenin. Consequently, the tumor was diagnosed as an MM with rhabdoid cell differentiation. This case highlights a potential diagnostic pitfall, as the morphological and immunohistochemical features may closely mimic those of collision tumors and myogenic tumors.
