1 · What the graph read from it

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.

2 · The registry

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

objectivesIncomplete interlobar fissure complicates lobectomy and raises the risk of prolonged postoperative air leak. Although the fissureless fissure-last approach can reduce air leak in thoracoscopic surgery, its applicability in robot-assisted thoracoscopic surgery for left lower lobectomy remains uncertain. This study evaluated the feasibility of the fissureless fissure-last approach by comparing perioperative outcomes with those of the conventional interlobar approach.

methodsThis single-center retrospective study included 53 patients with primary lung cancer who underwent robot-assisted left lower lobectomy between November 2019 and November 2024. They were divided into a fissureless fissure-last group (n = 13) and a conventional interlobar group (n = 40), and perioperative outcomes were compared.

resultsPatient characteristics did not differ significantly between the groups. The severe incomplete interlobar fissure proportion was significantly higher (77% vs. 10%, p < 0.001) and operative time significantly longer (190 vs. 152 min, p = 0.011) in the fissureless fissure-last group. No conversions to thoracotomy or major intraoperative complications occurred in either group. Duration of chest drain, postoperative hospital stay, and postoperative complications were comparable between the groups. The incidence of prolonged postoperative air leak was 0% (0/13) in the fissureless fissure-last group and 5% (2/40) in the conventional interlobar group; however, the difference was not statistically significant.

conclusionsThe fissureless fissure-last approach in robot-assisted left lower lobectomy appears to be a safe and feasible alternative for selected patients with severe incomplete interlobar fissure.
