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
introductionThe aim of this study was to evaluate the efficacy of the 4-hook needle localization for pulmonary ground glass nodules (GGNs).
methodsFrom November 1, 2021, to May 31, 2024, 194 patients were diagnosed with one or more GGNs by computed tomography (CT) scan and underwent preoperative CT-guided 4-hook needle localization followed by video-assisted thoracoscope surgery (VATS) wedge resection, segmentectomy or lobectomy. There were 226 nodules in all patients. We analyzed the 4-hook needle localization safety, complications, safe margin and localization depth.
resultsThe 4-hook needle localizations success rate was 100% and didn't take place in displacement and dislodgment. The tumor margin distance is about 5-20 mm and all tumor margin was negative thorough final pathology result. 9 patients occurred small parenchymal hemorrhage, 13 patients occurred small pneumothorax and 8 patients occurred small hemoptysis, those complications needn't intervene or tackle and didn't affect surgery. Compared upper and middle lobe to lower lobe, localization time was 13.92 ± 4.6 min vs 13.66 ± 4.28 min respectively, p = 0.69, there was no significant statistical difference. Localization depth was 18.63 ± 7.8 mm vs 15.87 ± 8.52 mm respectively, p = 0.02, there were statistical differences, but the margin tumor distance was 5.16 ± 4.94 mm vs 4.93 ± 3.64 mm, p = 0.73 respectively, there was no statistical difference.
conclusionsPreoperative 4-hook needle localization is safe and feasible for GGNs. Guided by 4-hook needle localization, wedge resection can ensure enough safe margins and patient was well tolerated.
