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
Background: The benefits of intraoperative nerve monitoring for identifying recurrent laryngeal nerves during esophageal cancer surgery have recently been reported. However, no standardized procedures have been established for the use of this system. This study aimed to identify factors affecting the diagnostic accuracy of intraoperative nerve monitoring for recurrent laryngeal nerve palsy and explore approaches to improve the precision and efficiency of intraoperative nerve monitoring in esophageal cancer surgery. Methods: We analyzed 187 consecutive patients who underwent esophagectomy between 2011 and 2018, of whom 142 underwent intraoperative nerve monitoring. We evaluated factors affecting the diagnostic accuracy of intraoperative nerve monitoring for recurrent laryngeal nerve palsy. Results: The overall incidence of postoperative recurrent laryngeal nerve palsy was 22% (32/142). Univariate analysis identified the left lateral decubitus position (vs. prone position) and not using video laryngoscope during intubation as risk factors for discrepancies between intraoperative nerve monitoring findings and postoperative recurrent laryngeal nerve palsy diagnosis. Multivariate analysis confirmed that the left lateral decubitus position (odds ratio: 4.24; 95% confidence interval: 1.09-13.4, Conclusion: Adequate contact between the intubation tube and vocal cord muscles is crucial for effective intraoperative nerve monitoring during esophagectomy. Additionally, the intraoperative posture significantly affects diagnostic outcomes and should be carefully considered.
