Evaluation of cytomorphological examination in the diagnosis of pleural effusion.
Article in Clinical and experimental medicine, 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
Cytological examination serves as a crucial diagnostic tool for pleural effusion, with its diagnostic efficacy influenced by variations in specimen processing and staining techniques. Cellular morphological analysis of pleural effusions was performed using Wright-Giemsa staining to assess its diagnostic accuracy and clinical utility in differentiating the various etiologies of exudative pleural effusion. A routine examination was conducted on 2305 cases of unexplained pleural effusion, followed by cellular classification and morphological analysis in 1376 cases identified as exudative effusion. Among the 479 patients with malignant tumors, cytomorphological examination identified malignant cells in 295 patients, resulting in a clinical diagnosis coincidence rate of 98.6%. Abnormal cells, including malignant and heterogeneous nuclear cells, were observed in 364 cases, yielding a detection rate of 76.0%. The proportion of positive malignant cells in the newly diagnosed patient group was significantly higher than that in the previously diagnosed group (P < 0.01). Cytological analysis revealed the presence of bacteria, fungi, and phagocytes in 51 out of 1376 cases. The positivity rate for multiple bacterial infections detected through cytology was significantly greater than that identified by culture (P < 0.01). Additionally, various special morphologies and pathogens, which are rare in clinical practice, were detected, including mixed metastasis of small cell lung carcinoma and adenocarcinoma cells, as well as concurrent infections with Talaromyces marneffei and Pneumocystis jirovecii. This method enables the rapid and comprehensive differentiation between malignant tumors, tuberculosis, pneumonia, and rare exudative pleural effusions resulting from specific clinical conditions.
