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
purposeThis study aimed to compare surgical safety outcomes of uniportal and multiportal video-assisted thoracoscopic surgery (uVATS and mVATS) segmentectomy during institutional adoption, focusing on differences according to lobar location.
methodsWe retrospectively analyzed 117 patients who underwent thoracoscopic segmentectomy between 2019 and 2024 (uVATS, 49; mVATS, 68). Outcomes included intraoperative pulmonary vessel injury and major postoperative complications, along with operative time, blood loss, and length of hospital stay. Inverse probability of treatment weighting was applied, and analyses were performed overall and stratified by lobe.
resultsPulmonary vessel injury occurred in 12 patients (10.3%), and grade ≥III complications in 10 (8.5%). After adjustment, uVATS showed a higher incidence of vascular injury than mVATS overall (22.8% vs. 5.5%; p = 0.006). No statistically significant differences were observed in upper-lobe segmentectomy. In lower-lobe segmentectomy, uVATS showed higher rates of vascular injury (44.8% vs. 2.2%; p <0.001) and grade ≥III complications (18.8% vs. 0%; p = 0.005).
conclusionsNo statistically significant differences were observed between uVATS and mVATS in upper-lobe segmentectomy. However, during the institutional adoption phase, careful consideration is warranted when performing lower-lobe segmentectomy with uVATS due to a higher incidence of complications related to surgical safety.
