The morphological characteristics and arrangements of cells in the liquid-based cytology preparation of patients with endometrial lesions.
Article in Diagnostic pathology, 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
backgroundThe accurate cytological diagnosis of endometrial carcinomas by minimally invasive method has a broad application. There are several articles described the morphological characteristics but not arrangements of endometrial lesion cells on LBC slides.
methodsA retrospective study was conducted using 175 endometrial samples obtained by direct negative pressure suction with disposable endometrial sampler. All lesions were diagnosed both cytologically and histologically, and the diagnostic results were compared and analyzed.
resultsThe cytological diagnoses of polyps, simple or complex hyperplasia, and atypical hyperplasia were highly consistent with the histological diagnosis. The cytological features of polyps and normal endometrium, as well as simple and complex hyperplasia, are the same. Among 82 cases of histologically confirmed adenocarcinoma, the cytological diagnosis were adenocarcinoma cells (46 cases, 56.10%), suspected for adenocarcinoma cells (22 cases, 26.83%), and false negative (14 cases,17.07%). Retrospective reviewing the slide suggest diagnostic parameters such as significantly enlarged nuclei, multistage papillary arrangements, large and numerous nucleoli, and large vacuoles containing neutrophils in the cytoplasm are reliable diagnostic criteria for endometrial carcinoma cells; on the other hand, ignorance of lobulated arrangements and escaped arrangements are the main reasons for missed diagnosis.
conclusionsThe cytological diagnosis of endometrial lesions not only depends on the morphological characteristics of cells, but also need careful observations of the cellular arrangements.
