Comparison of extended segmentectomy with traditional segmentectomy for stage I lung cancer.
Article in Journal of cardiothoracic surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundFor stage I non-small cell lung cancer (NSCLC), lobectomy and segmentectomy are still controversial operations. Extended segmentectomy was proposed to make larger safe margins than segmentectomy. Image-guided video-assisted thoracoscopic surgery (iVATS) is useful to accomplish extended segmentectomy. We aimed to compare the effects of iVATS extended segmentectomy to the effects of traditional segmentectomy for stage I NSCLC.
methodsThis study is a retrospective analysis in a single institute. Patients with stage I NSCLC who received segmentectomy between January 2017 and September 2020 were included. Patients were distributed to iVATS extended segmentectomy (group A), and traditional segmentectomy (group B). The impacts of the different surgical methods on resection margin were assessed.
resultsThere were 116 patients enrolled in this study. Sixty-two patients distributed in group A, and the other 54 patients in group B. The resection margin to a staple line was 17.94 mm in group A versus 14.15 mm in group B, p = 0.037. The margin/tumor diameter ratio was 2.08 in group A versus 1.39 in group B, p = 0.003. The enough margin rate was 75.81% and 57.41%, respectively, for group A and group B. The subgroup analysis of iVATS extended segmentectomy showed that T1a lesions had larger margin distances than did T1b lesions (19.85 mm vs. 14.83 mm, p = 0.026).
conclusionsThe iVATS extended segmentectomy can provide more resection margin than traditional segmentectomy. Segmentectomy is more suitable to perform when the nodule's diameter is less than 10 mm.
