Thoracoscopic segmentectomy for trans-fissure ground-glass opacity.
Article in Interdisciplinary cardiovascular and thoracic surgery, 2024. 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
objectivesThe trans-fissure ground-glass opacity (GGO) is a special category of lesions, with a diameter always exceeding 2 cm. It is located on a fused fissure, 'seizing' 2 neighbouring lobes simultaneously. The segmentectomy for the trans-fissure GGO is never reported.
methodsBetween August 2016 and December 2022, patients operated with a trans-fissure GGO were included. The patients' backgrounds and surgical data were summarized. All procedures were performed with the help of preoperative three-dimensional computed tomography bronchography and angiography.
resultsA total of 84 patients were included. The selection criteria included a consolidation tumour ratio <50% and a lesion size >2 and ≤3 cm. Thirty-six patients were operated with lobectomy + wedge (the traditional method group) and 48 patients were operated with anatomical segmentectomy + function-preserving sublobectomy (the new method group). The median operative time was 87 min in the traditional group and 98 min in the new method group, and the median blood loss was 60 ml in the traditional group and 70 ml in the new method group. The median duration of hospital stays was 4 days in the traditional group and 2 days in the new method group. In the traditional method group, there was 1 case of postoperative air leakage and 5 cases of haemoptysis. In the new method group, 2 cases of postoperative air leakage were identified. The median size of the tumour in the resected segment was 2.6 cm in the traditional group and 2.5 cm in the new method group. The median margin was 2.5 cm in the traditional group and 3.3 cm in the new method group.
conclusionsThe trans-fissure GGO could be safely resected en bloc by segmentectomy with a well-designed surgical procedure and appropriate preoperative planning.
