Uniportal subxiphoid thoracoscopic thymectomy with the Tian-Ping sternal lifter: a prospective non-randomized comparative study.
Article in Journal of thoracic disease, 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
Background: Conventional minimally invasive thymectomy (MIT) can be limited by insufficient retrosternal exposure, while existing sternal elevation techniques still have technical limitations. This study aimed to introduce a novel percutaneous suspension-assisted subxiphoid thoracoscopic thymectomy with Tian-Ping sternal lifter and compare its perioperative outcomes to conventional MIT. Methods: The single-center prospective observational study with a non-randomized comparative design was conducted between June 2024 and June 2025. Consecutive adult patients with resectable anterior mediastinal masses scheduled for MIT were enrolled. Group A underwent uniportal subxiphoid thymectomy using the Tian-Ping sternal lifter, and Group B underwent conventional MIT. Treatment allocation was based on patient preference and surgeon judgment. The primary outcome was postoperative pain, assessed using visual analog scale (VAS) scores on postoperative days 1, 3, 7, and 30. Secondary outcomes comprised perioperative indicators of surgical safety and feasibility, including 30-day postoperative complications. Propensity score matching was used to improve baseline comparability between the groups, after which the primary and secondary outcomes were compared between the matched groups. Results: A total of 139 patients [mean (standard deviation, SD) age, 49.5 (12.0) years; 71 females (51.1%)] were included after one preoperative exclusion, with 50 in the Group A and 89 in the Group B. After propensity score matching, 49 patients remained in each group, with comparable baseline characteristics. In the matched cohort, Group A had lower VAS scores than Group B on postoperative day (POD) 1 [median (interquartile range, IQR), 1.00 (0.00-1.00) Conclusion: Tian-Ping sternal lifter-assisted uniportal subxiphoid thymectomy was feasible and associated with lower early postoperative pain scores and favorable short-term outcomes.
