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

Background: Accurate localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging due to the small size and deep location. Both the 4-hook wire technique and methylene blue are significant methods for preoperative localization of SPNs. This study aimed to compare the safety of both methods by monitoring and recording any surgery-related complications. Additionally, the effectiveness of both methods was compared by measuring the success rate of localization and the time required for both localization and resection of the nodules. Methods: Patients who underwent computed tomography (CT)-guided lung nodule localization before VATS from May 2021 to April 2023 at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were analyzed retrospectively. A total of 75 patients with 84 SPNs were included in this study, comprising 35 4-hook anchor patients with 41 SPNs and 40 methylene blue-marked patients with 43 SPNs. Results: The VATS operative time for SPNs in the 4-hook anchor device group was significantly shorter than that in the methylene blue group (57.4±12.4 Conclusions: Compared with the methylene blue technique, the 4-hook anchor device is safe and reliable and offers a shorter VATS operative time.
