Diagnostic Pitfalls in Fine Needle Aspiration of Pleomorphic Adenoma: Degenerative Changes in Myoepithelial Cells as Malignant and PLAG1 False Negativity.
Article in Diagnostic cytopathology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Fine needle aspiration (FNA) is widely accepted as an efficient first-line diagnostic tool for evaluating salivary gland lesions. It can accurately diagnose a majority of common benign tumors, including pleomorphic adenoma (PA). However, PA can exhibit a wide range of morphological variations, which may lead to misinterpretation. Here, we present a case in which degenerative myoepithelial cells with nuclear atypia in PA were misinterpreted as malignant. Furthermore, PLAG1 false negativity in cell block material compounded the diagnostic challenge. This report aims to highlight this diagnostic pitfall and alert cytopathologists by providing an illustrative example.
