Investigation of the Prevalence of Chronic Pulmonary Effusion Causes and Response to Treatment (Pleurodesis) in Patients.
Article in The open respiratory medicine journal, 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
Background: Pleural effusion, the pathological accumulation of fluid in the pleural space, is widespread. This study investigates pleural effusion in terms of malignancy among patients referred to tertiary health care centers and evaluates the response rates to different pleurodesis techniques. Methods: This cross-sectional study enrolled all patients with pleural effusion referred to a tertiary health care center. Laboratory data, including White Blood Cell count and differentiation (WBC), Hemoglobin levels (HB), Erythrocyte Sedimentation Rate (ESR), and biochemical analysis results of the pleural fluid (protein, glucose, and lactate dehydrogenase) were recorded. Data from pleural fluid cytopathological examination, including cell count, cell types, gram staining, and pleural fluid culture, were also documented. Patients undergoing pleurodesis were assessed for response rates, which were categorized as complete, partial, or no response based on clinical and radiological criteria. Collected data were subjected to statistical analysis. Results: The study investigated 144 patients with chronic pleural effusion, with an average age of 47.59 years. Of these, 97 patients (66%) were male and 47 patients (34%) were female. The most common cause of chronic pleural effusion was malignancy, with a prevalence of 65.9%. Among patients treated with pleurodesis, the overall response rate was 78.4%, with chemical pleurodesis achieving a higher complete response rate (65%) compared to mechanical pleurodesis (55%). Other prevalent causes of chronic pleural effusion, in descending order, included heart failure, liver cirrhosis, chronic kidney failure, and unknown factors. Conclusion: This study highlights malignancy and chronic heart failure as the predominant etiologies of chronic pleural effusion in a tertiary healthcare setting. Furthermore, it emphasizes the efficacy of pleurodesis techniques, with chemical pleurodesis demonstrating superior outcomes. These findings offer valuable insights into the pathogenesis and management of chronic pleural effusion.
