Tumor-to-thoracic height and width ratios as adjunct imaging markers for preoperative risk stratification in minimally invasive surgery for pediatric mediastinal masses.
Article in Pediatric surgery international, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeSelecting the optimal surgical approach for pediatric mediastinal masses is challenging because absolute tumor size does not adequately reflect the available intrathoracic working space in children. This study evaluated whether the tumor-to-thoracic height ratio (TTH) and tumor-to-thoracic width ratio (TTW) are associated with intraoperative complications during minimally invasive surgery (MIS).
methodsSixty-five children who underwent surgical resection of mediastinal masses between 2007 and 2025 were retrospectively reviewed. Fifty-six underwent MIS, and nine underwent open thoracotomy. TTH and TTW were calculated using preoperative chest radiography and computed tomography or magnetic resonance imaging. Associations with intraoperative complications in the MIS group were analyzed, and receiver operating characteristic analysis was performed as an exploratory assessment.
resultsIntraoperative complications occurred in five of 56 patients undergoing MIS. Both TTH and TTW were significantly higher in patients with complications than in those without (TTH: 0.51 vs. 0.26, p = 0.004; TTW: 0.67 vs. 0.37, p = 0.005). Positive image-defined risk factors were also more frequent in patients with complications. The area under the curve was 0.894 for TTH and 0.882 for TTW.
conclusionTTH and TTW may serve as useful exploratory adjunct imaging markers for preoperative risk stratification in pediatric MIS for mediastinal masses.
