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
introductionMedian sternotomy can cause postoperative adhesions, raising bleeding and organ damage risks during resternotomies. Computed tomography angiography (CTA) and extended reality (XR) are increasingly used to enhance surgical planning and minimize these risks. This study aims to assess the benefits of integrating XR technology into resternotomy planning.
methodsThis multi-center study, conducted at the Sheba and Wolfson Medical Centers in Israel, evaluated the utility of three-dimensional imaging in surgical resternotomy planning in 24 cases. Pediatric and adult patients selected for resternotomy underwent routine CTA, and those with adequate image quality were used to generate virtual three-dimensional segmentation. The images were evaluated preoperatively.
resultsThe findings indicated no significant benefit of XR over CTA in terms of resternotomy anatomical data. However, the accuracy of the XR models varied with medical experience: senior physicians rated the XR as less accurate for adult patients than did residents, but the ratings were high in both groups for pediatric cases. The XR models improved the surgeons' understanding of chest anatomy in pediatrics more than in adult patients, whereas for surgical decision-making, XR was seen as more beneficial in pediatric cases, particularly by senior surgeons. Overall, senior physicians reported that XR influenced their surgical decisions more, suggesting that the utility of XR varies with physician experience and patient age.
conclusionXR technologies have shown considerable potential in enhancing visualization and contributing to determining surgical strategies. However, the extent of their influence in terms of reducing operative durations and minimizing intraoperative complications requires further investigation.
