CT-guided coaxial four-hook localization improves precision and efficiency in video-assisted thoracoscopic surgery: a retrospective study.

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: With the increasing detection of small and indeterminate pulmonary nodules in the era of low-dose computed tomography (CT) screening, accurate preoperative localization has become critical for successful video-assisted thoracoscopic surgery (VATS), particularly for non-palpable lesions. This study aimed to evaluate and compare the effectiveness and complication profiles of 3D image reconstruction and a novel CT-guided coaxial four-hook localization system. Methods: This retrospective study included patients who underwent VATS for pulmonary nodules, guided by either 3D image reconstruction (n=273 nodules) or CT-guided coaxial four-hook localization (n=255 nodules). Clinical and imaging variables were compared, including nodule characteristics, surgical approach, operative time, hospital stay, and complication rates. Multivariate logistic regression was performed to identify independent risk factors for procedure-related complications. Results: Both the 3D image reconstruction group and CT-guided localization group achieved high localization success rates (98.5% Conclusions: Both 3D image reconstruction and CT-guided localization are safe and effective for preoperative guidance in VATS. The CT-guided method provides superior intraoperative precision and efficiency, particularly in managing small, pure ground-glass nodules and in cases requiring function-preserving wedge resections.
