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 intraoperative localization of nonpalpable pulmonary nodules for thoracoscopic wedge resection is technically challenging. Current preoperative image-guided localization techniques require additional time, costs, procedural risks, advanced facilities, and well-trained operators. In this study, we explored a cost-effective method of well-matched interaction between virtuality and reality for accurate intraoperative localization. Methods: Through the integration of techniques involving preoperative 3-dimensional (3D) reconstruction, temporary clamping of target vessel and the modified inflation-deflation method, the segment on the 3D virtual model and the segment under the thoracoscopic monitor were well matched in the inflated state. Then the spatial relationships of target nodule to the virtual segment could be applied to the actual segment. The well-matched interaction between virtuality and reality would facilitate nodule localization. Results: A total of 53 nodules were successfully localized. The median maximum diameter of the nodules was 9.0 mm (interquartile range [IQR], 7.0-12.5 mm). The median depth Conclusions: The well-matched interaction between virtuality and reality is safe and feasible for intraoperative localization of nonpalpable pulmonary nodules. It may be proposed as a preferred alternative to traditional localization methods.
