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
purposeIn totally endoscopic off-pump left atrial appendage (LAA) closure and surgical ablation, securing the operative field is sometimes difficult in some patients because of a narrow working space caused by an elevated diaphragm or ventricles. In this study, we aimed to investigate the effectiveness of a method that facilitates securing the operative field using an artificial pneumothorax.
methodsWe analyzed 71 consecutive patients who underwent totally endoscopic off-pump LAA closure and bilateral pulmonary vein isolation. The factors contributing to the reduction in operative time were examined. The patients were divided into the following 2 groups according to whether or not an artificial pneumothorax was used: Group C comprised 24 patients without an artificial pneumothorax and Group A comprised 47 patients with an artificial pneumothorax.
resultsThere were no hospital deaths or major complications. The operative time was significantly shorter in Group A (108 ± 26 minutes) than in Group C (198 ± 77 minutes) (p <0.0001).
conclusionsIn totally endoscopic off-pump LAA closure and surgical ablation, an artificial pneumothorax may be useful in reducing the operative time.
