Five-year Experience of Using Single Port Rigid Thoracoscopy in Patients of Undiagnosed Exudative Pleural Effusion at Tertiary Center in North India.
Article in Annals of African medicine, 2026. 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
backgroundPleural effusion is one of the common pleural diseases encountered by pulmonologists worldwide. Malignancy and tuberculosis are the two most common etiologies in such patients, who have completely different prognoses. Pleural biopsy is the gold standard investigation to diagnose various causes of pleural effusion. Rigid Medical Thoracoscopy is a semi-invasive tool to evaluate the pleura morphologically and take an image-guided biopsy from the pleura for a definitive diagnosis. MATERIALS AND
methodsThis was a single-center, retrospective data-based study. Data were collected between January 1 st , 2020, and December 31 st , 2024. Patients with undiagnosed exudative pleural effusion, defined as negative cartridge based nucleic acid amplification for tuberculosis and twice negative pleural fluid cytology for malignancy, underwent rigid thoracoscopy to confirm their diagnosis.
resultsA total of 376 patients underwent thoracoscopy. The mean age of the patients was 58.8 years, and male-to-female ratio was 1.3:1. The most common etiology observed was malignancy, seen in 275 patients (73.1%), followed by tuberculosis in 66 patients (17.5%) and nonspecific inflammation in 25 patients (6.7%). A final diagnosis could be made in 369 patients, giving a diagnostic yield of 98.1%. It was also used to break septations, which ultimately led to the expansion of their lung in 10 patients. Fifteen patients (4%) had major complications, whereas 31 patients (8.2%) had procedure-related minor complications.
conclusionRigid medical thoracoscopy has a very high diagnostic yield with few complications in the diagnosis of exudative pleural effusion. Therefore, tissue-based biopsy with thoracoscopy can be easily performed to make a correct diagnosis with huge future implication in such patients.
