Optimizing the dissection of small-diameter pulmonary vessels using vessel-sealing systems.
Article in Scientific reports, 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
Although vessel-sealing systems have been shown useful for dissection of small-diameter vessels, no studies to date have evaluated the optimal angle of dissection. Lateral thermal damage to a canine pulmonary artery was assessed microscopically. Burst pressure was compared in swine carotid arteries undergoing orthogonal and oblique dissections to determine the safer dissection technique. Histological analysis of a canine model revealed a thermal spread of approximately 1.3 mm. Burst pressure comparison showed no significant differences between orthogonal and oblique dissection angles (829.2 mmHg [range 608-1214 mmHg] vs. 949.1 mmHg [range, 593-1306 mmHg], P = 0.206). In a surrogate arterial model, burst pressure did not differ between orthogonal and oblique cuts. Given histologically limited lateral thermal spread on PA, angle may be less critical than avoiding vessel tension. These findings may contribute to the safer application of vessel-sealing systems in patients undergoing minimally invasive thoracic surgery.
