Long-term outcomes of virtual-assisted lung mapping compared with CT-guided percutaneous marking.
Article in Journal of thoracic disease, 2026. 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
Background: Virtual-assisted lung mapping (VAL-MAP) is a preoperative bronchoscopic multi-spot dye-marking technique that utilizes virtual bronchoscopy images to aid in the resection of pulmonary nodules that are difficult to identify intraoperatively. In this study, we compared the long-term oncologic outcomes of VAL-MAP with those of historical computed tomography (CT)-guided percutaneous marking. Methods: This retrospective observational study included 213 consecutive patients who underwent curative pulmonary resection from 1998 to 2018 at our institute. Patients who underwent VAL-MAP were compared with those who underwent CT-guided localization. The local recurrence rate and local recurrence-free survival were evaluated. Results: In total, 163 patients underwent sublobar pulmonary resection. Age and surgical procedure were significantly different between the VAL-MAP and CT-guided localization groups. The local recurrence rate was significantly lower in the VAL-MAP group than in the CT-guided localization group [2.9% Conclusions: VAL-MAP demonstrated favorable long-term outcomes for both local recurrence and local recurrence-free survival compared with CT-guided percutaneous marking.
