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
introductionLymphangioleiomyomatosis (LAM) is a rare systemic disease characterized by progressive cystic destruction of the lung parenchyma, resulting in extreme parenchymal fragility. Surgical treatment of lung cancer in patients with LAM is technically challenging due to the high risk of intractable air leaks. We report a case of robot-assisted thoracoscopic surgery (RATS) for lung cancer in a patient with LAM, highlighting a strategic hybrid approach to managing the exceptionally fragile lung tissue. CASE PRESENTATION: A 56-year-old woman with tuberous sclerosis complex-associated LAM was diagnosed with Stage IA1 adenocarcinoma in the left upper lobe. We performed a RATS left upper lobectomy using the da Vinci Xi system (Intuitive Surgical, Sunnyvale, CA, USA). To protect the exceptionally fragile lung, a "no-touch" retraction technique was employed using rolled gauze and blunt-tipped robotic instruments. A fissureless technique was applied to minimize parenchymal injury. Crucially, for the division of the incomplete interlobar fissure and the bronchus, we utilized manual staplers equipped with bioabsorbable reinforcement material (buttressed staplers) deployed by a bedside assistant, which provided superior sealing for the fragile lung compared to the robotic staplers available at that time. Despite these precautions, a pinhole air leak occurred in the S8 segment, likely due to unintentional contact with a robotic joint, illustrating the extreme sensitivity of the LAM lung. This was identified via a meticulous sealing test and repaired with polyglycolic acid sheets and fibrin glue. The patient was discharged on POD 5 without persistent air leaks. At 1 year post-surgery, her respiratory function was well-preserved, exceeding predicted values.
conclusionsRATS offers superior visualization for lung cancer surgery in patients with LAM. However, given the extreme fragility of the lung, the selective use of manual buttressed staplers is a vital adjunct to prevent postoperative air leaks. Optimal outcomes depend on a constant awareness of lung fragility, a hybrid technical strategy, and a rigorous intraoperative sealing test to identify and repair even minor pleural injuries.
