This study aimed to identify key factors influencing treatment outcomes, and to develop and integrate a predictive efficacy scoring tool with a clinical decision pathway to provide evidence-based treatment recommendations for pediatric PC patients.<\/jats:p>\n                  <jats:p>In this retrospective study, 182 pediatric PC patients evaluated and followed using three-dimensional scanning were enrolled. A multiple linear regression model was developed to create and validate a predictive efficacy scoring tool, which subsequently informed the establishment of a treatment decision pathway.<\/jats:p>\n                  <jats:p>The predictive model identified smaller initial external thoracic width (p\u2009&lt;\u20090.001, \u03b2\u2009=\u2009\u2212\u20090.644), older age at treatment initiation (p\u2009=\u20090.04, \u03b2\u2009=\u20090.271), good compliance (p\u2009=\u20090.008, \u03b2\u2009=\u20090.188), and favorable chest wall morphology (p\u2009=\u20090.033, \u03b2\u2009=\u20090.152) as independent predictors of deformity improvement. The model was optimized into a predictive efficacy scoring tool (Score\u2009=\u2009Expected %dEHI\u2009+\u20094.761). Comparison between the good response (score\u2009&gt;\u20090) and poor response (score \u2264 0) groups confirmed the tool's excellent discriminative ability (8.348 vs. 15.320, p\u2009&lt;\u20090.001).<\/jats:p>\n                  <jats:p>Treatment recommendations were derived by integrating the scoring tool with the decision pathway: children with score\u2009&gt;\u20090 are strongly recommended to continue bracing; those with score \u2264 0 due to poor compliance should receive intensified supervision, while those with score \u2264 0 due to other factors should be counseled on possible surgery; children under 4 years require personalized recommendations integrating the score, symptoms, and parental preferences. However, as a single-center retrospective study without a control group and with subjective compliance assessment, future prospective multicenter studies are required to validate the model's generalizability.<\/jats:p>","DOI":"10.1055\/a-2782-7127","type":"journal-article","created":{"date-parts":[[2026,1,9]],"date-time":"2026-01-09T23:55:24Z","timestamp":1768002924000},"page":"305-315","source":"Crossref","is-referenced-by-count":0,"title":["Development
