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

Multiple myeloma is a malignancy characterized by the monoclonal proliferation of plasma cells, primarily within the bone marrow. While it predominantly remains confined to the marrow, extramedullary plasmacytomas, though rare, can occur in various anatomical sites. This report presents three cases of extramedullary plasmacytomas in uncommon locations (the thyroid, pleura, and skin) in patients with an established diagnosis of multiple myeloma. Each case was diagnosed using histopathological examination and immunohistochemical profiling. The thyroid plasmacytoma was identified through thyroid lobectomy, while pleural and cutaneous involvements were detected via biopsy of a pleural and a subcutaneous mass, respectively. These cases highlight the diversity of extramedullary plasmacytoma manifestations and underscore the importance of considering multiple myeloma in the differential diagnosis when atypical extramedullary tumors are identified.
