The usefulness of full-thickness biopsy during semi-rigid pleuroscopy for differentiating between malignant pleural mesothelioma and non-specific pleurisy.
Article in BMC pulmonary 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
backgroundMalignant pleural mesothelioma is a rare disease with a poor prognosis; distinguishing it from non-specific pleurisy is essential for determining an appropriate treatment strategy. We aimed to evaluate the diagnostic utility and safety of full-thickness biopsy performed during semi-rigid pleuroscopy under local anaesthesia to differentiate between malignant pleural mesothelioma and non-specific pleurisy.
methodsConsecutive patients who attempted full-thickness biopsy using a cryoprobe or an insulated-tip diathermic knife during semi-rigid pleuroscopy between April 2019 and October 2023 were retrospectively enrolled. The diagnostic utility of full-thickness biopsy for distinguishing malignant pleural mesothelioma from non-specific pleurisy was assessed based on diagnostic accuracy, specimen quality, and procedural safety.
resultsAmong the 64 patients who underwent full-thickness biopsy, 28 diagnosed with malignant pleural mesothelioma or non-specific pleurisy were included in this study. With the exception of one malignant pleural mesothelioma case diagnosed by surgical biopsy, 13 malignant pleural mesothelioma and 14 non-specific pleurisy cases were histologically diagnosed through full-thickness biopsy, with clinical courses supporting these diagnoses. The median full-thickness biopsy specimen size was 18.8 mm² (range: 0.6-364.2 mm
conclusionFull-thickness biopsy during semi-rigid pleuroscopy provides high diagnostic accuracy and safety for differentiating malignant pleural mesothelioma from non-specific pleurisy, while yielding high-quality pleural tissue specimens.
