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: Computed tomography (CT)-guided percutaneous transthoracic lung biopsy is an important method for obtaining pathological diagnoses of pulmonary lesions. However, conventional manual localization and needle advancement are operator dependent, and technically difficult lesions may require repeated angle adjustments and CT acquisitions. The aim of this study was to evaluate the procedural efficiency, diagnostic performance, and safety of a novel positioning grid combined with a non-coplanar puncture-angle guide. Methods: This single-center, retrospective, nonrandomized contemporaneous-control study included 287 patients who underwent CT-guided percutaneous transthoracic lung biopsy between August 2023 and November 2024. The device group comprised 146 patients treated using the novel positioning grid and angle guide, whereas 141 controls underwent biopsy using a conventional positioning grid without the angle guide. Procedure time, number of CT acquisitions, diagnostic yield, and complications were compared. Multivariable binary logistic regression was used to identify factors associated with pneumothorax. Results: Procedure time was shorter in the device group than in the control group (7.47±2.69 Conclusions: Use of the novel positioning grid combined with a non-coplanar puncture-angle guide was associated with shorter procedure time, fewer CT acquisitions, and lower rates of pneumothorax and hemoptysis while maintaining a high diagnostic yield. Prospective multi-operator studies are warranted because the present study was nonrandomized and the groups were treated by different operators.
