Preliminary clinical experience with a robot-assisted system in preoperative hookwire localization of pulmonary nodules: a prospective pilot 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
Accurate preoperative localization is critical for the surgical resection of small pulmonary nodules, yet conventional CT-guided hookwire placement remains operator-dependent and technically demanding. This prospective study evaluated the clinical performance of a robot-assisted navigation system for CT-guided preoperative hookwire localization of pulmonary nodules. The trial enrolled 60 patients scheduled for localization followed by VATS. Primary endpoints included first-attempt puncture success rate, needle placement accuracy, localization success rate, procedure duration, number of punctures, radiation dose, and complication rate, with subgroup analyses by lesion characteristic and patient positioning. The first-attempt puncture success rate was 100.0%, with an median needle placement accuracy of 5.7 mm (IQR 4.2-7.9). Localization success was achieved in 94.8% of nodules (55/58). The median procedure duration was 16.6 min (14.0-22.9), and the median radiation dose was 281.2 mGy·cm (227.1-365.8). The overall complication rate was 5.2% (3/58). Accuracy was consistent across subgroups, although lower lobe lesions and prone positioning were associated with longer procedure times, and prone positioning also increased radiation exposure, without compromising accuracy. These findings demonstrate the feasibility, precision, and safety of this system, supporting its potential to standardize and improve preoperative localization in thoracic surgery.
