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: Although the soft hook-wire has been designed to be less traumatic than rigid devices, localization-related complications are still at risk to perioperative safety. This study aimed to find out independent risk factors for these complications in solitary pulmonary nodules patients (SPNs) and create a new nomogram for exact risk stratification. Methods: Retrospectively analyzed 244 consecutive patients who underwent CT-guided soft hook-wire localization and subsequently had video-assisted thoracoscopic surgery for SPNs in our department from January 2025 to November 2025. Univariate and multivariate logistic regression analysis was done to find out independent predictors for complications. According to these factors, we developed and evaluated a prognosis nomogram. Results: Technical success rate of localization was 100%. Post-procedural complications occurred in 71 (29.1%) patients. Complications were restricted to pneumothorax and pulmonary hemorrhage. After multivariate analysis, it was found that the presence of emphysema (OR: 15.45, Conclusion: The prediction nomogram developed in this study exhibits good accuracy in predicting complications following CT-guided soft hook-wire localization of SPNs and provides an objective tool for clinical staff to assess preoperative risk.
