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

objectivesThis study evaluates the initial surgical results of our proposed minimally invasive extended thymectomy procedure using the "lateral view preceding method," which precedes dissection of the lower poles of the thymus and mediastinal fat around the cardiophrenic angles with lateral thoracoscopic views, followed by a robot-assisted subxiphoid approach for the remaining extended thymectomy.

methodsThe lateral view preceding method was introduced in October 2020. We retrospectively reviewed patients with suspected thymomas in the anterior mediastinum having anti-acetylcholine receptor antibodies who underwent minimally invasive extended thymectomy between April 2011 and April 2025. Surgical outcomes were analyzed and compared with those of conventional bilateral video-assisted thoracic surgery.

resultsNine patients, seven of whom had myasthenia symptoms, underwent the lateral view preceding approach. Mean operative, pre-robot, and robot console times were 261 ± 43, 79 ± 20, and 144 ± 28 min, respectively. No postoperative complications were observed. All patients with myasthenic symptoms showed improved minimal manifestations and better status. Compared with patients who underwent the lateral view preceding method, those who underwent the conventional approach (21 patients) had more ports (mean, 8.4 ± 1.3 and 4.2 ± 0.5, respectively, p < 0.001) and longer operative time (mean, 346 ± 117 min and 261 ± 43 min, respectively, p  = 0.024). Postoperative complications occurred in five (31%) patients who underwent the conventional approach.

conclusionExtended thymectomy using the lateral view preceding method resulted in safe and effective initial surgical outcomes. We believe that this is a promising and minimally invasive approach.
