Prospective Evaluation of Cardiovascular, Pulmonary, and Biochemical Changes Following Minimally Invasive Repair of Pectus Excavatum in Children: Study Protocol.

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
backgroundPectus excavatum is the most common congenital chest wall deformity and it may impair cardiovascular function, pulmonary mechanics, exercise capacity, and quality of life. Although minimally invasive repair of pectus excavatum (MIRPE) is the current standard surgical treatment, the perioperative dynamics of myocardial injury, inflammation, and their relationship with functional and echocardiographic changes remain incompletely understood, particularly in pediatric patients.
objectiveThe objective is to prospectively evaluate the perioperative dynamics of cardiac troponin and the change in right ventricular free-wall longitudinal strain as co-primary endpoints, and-as secondary outcomes-additional biochemical markers, echocardiographic parameters, pulmonary function, exercise capacity, and quality of life in children and adolescents undergoing MIRPE.
methodsThis is a single-center, prospective, observational cohort study to be conducted at the Department of Pediatric Surgery and Urology, University Children's Clinical Hospital, Medical University of Bialystok, Poland. Sixty pediatric patients (approximately 14-18 years of age) undergoing primary minimally invasive repair of pectus excavatum will be enrolled. Biochemical markers, including troponins, natriuretic peptides and inflammatory markers will be assessed before surgery and during the first 72 h postoperatively. Echocardiography, pulmonary function tests (spirometry and body plethysmography), the 20 m shuttle run test (Léger), and quality-of-life assessments will be performed preoperatively and during postoperative follow-up. Longitudinal changes will be analyzed using appropriate statistical methods for repeated measurements. DISCUSSION: This study is expected to provide a comprehensive evaluation of the cardiovascular, pulmonary, biochemical, and functional consequences of minimally invasive repair of pectus excavatum in pediatric patients. The findings may improve the understanding of the perioperative myocardial response, cardiac remodeling, and functional recovery following the MIRPE and contribute to optimizing perioperative assessment and long-term follow-up in this patient population.
