Histopathological variations of Sclerosing Polycystic Adenoma: A systematic review.
Review in Journal of Taibah University Medical Sciences, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In this systematic review, we evaluated the histopathological variations of sclerosing polycystic adenoma (SPA). Databases including PubMed, ScienceDirect, OVID (MEDLINE), and grey literature sources were searched comprehensively. A total of 137 cases of SPA were identified across 66 selected articles. SPA predominantly affects the parotid glands of adults, with a mean age of 45.1 years, and has a slight female predominance. Clinically, SPA presents as a firm, painless mass with a prolonged evolution period. Histologically, SPA lesions were well demarcated, featuring ductal and acinar hyperplasia, cyst formation, and dense stromal fibrosis. Variability in epithelial cell morphology, stromal characteristics, and the presence of intraductal proliferation were notable findings. This review underscores the necessity of understanding the histopathological spectrum of SPA to enhance diagnostic precision and patient management. Despite its benign nature, SPA's complex histopathology necessitates extensive differential diagnosis, emphasizing the importance of a systematic approach in histopathological evaluation.
