Exercise testing outcomes after pectus excavatum repair: A 16-year experience.
Article in JTCVS open, 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
Objective: To evaluate changes in cardiopulmonary exercise testing (CPET) performance after minimally invasive repair of pectus excavatum (PE) in adults and to identify factors associated with postoperative functional improvement. Methods: This retrospective single-center cohort study included patients who underwent primary PE repair with preoperative CPET between January 2010 and January 2026. Patients with major comorbidities or concomitant cardiac surgery were excluded. Among 1443 patients, 846 had preoperative CPET; 488 (57.7%) underwent bar removal, and 326 (66.8%) completed paired postoperative CPET before removal. Changes in CPET parameters were analyzed using paired comparisons. Multivariable logistic regression identified predictors of >10% improvement in percent predicted peak oxygen uptake (Vo Results: Among 326 patients with paired CPET, mean (SD) time to postoperative testing was 45.8 (16.1) months. At baseline, 228 (70.0%) had reduced percent predicted peak Vo Conclusions: Minimally invasive repair of PE in adults is associated with significant improvements in several CPET parameters. Functional gains occur independently of symptom perception, whereas greater anatomical severity predicts larger improvement.
