Occlusal features in individuals with cerebral palsy: a systematic review and meta-analysis
Bibliographic record
Abstract
BACKGROUND: Cerebral palsy (CP) results from developmental abnormalities or brain lesions that impair movement, posture, and motor function, thereby affecting skeletal development, including craniofacial structures. OBJECTIVES: This study aimed to evaluate occlusal characteristics in individuals with and without CP. SEARCH METHODS: This systematic review followed Meta-Analysis of Observational Studies in Epidemiology guidelines. A comprehensive search was conducted in Embase, PubMed, Web of Science, Ovid, and Scopus, with additional screening of Google Scholar and OpenGrey. SELECTION CRITERIA: Observational studies were included, and the risk of bias was assessed using Newcastle-Ottawa Scale. DATA COLLECTION AND ANALYSIS: Meta-analyses were performed to estimate odds ratios (ORs) with 95% confidence intervals (CIs) and prediction intervals. The GRADE approach was used to evaluate the certainty of the evidence. RESULTS: Of the 584 records identified, 24 cross-sectional studies met the inclusion criteria. Risk-of-bias assessment revealed concerns related to exposure appraisal, nonrespondent characterization, and study comparability. The meta-analysis indicated that individuals with CP had a higher likelihood of Class II malocclusion (OR = 2.56, 95% CI: 1.49-4.38, k = 18) and open bite (OR = 4.27, 95% CI: 1.95-9.37, k = 9). CONCLUSIONS: Individuals with CP are at increased risk of developing Class II malocclusion and open bite, possibly due to neuromuscular dysfunctions and extrinsic factors. Effective management requires a multidisciplinary approach that addresses both biological and behavioral determinants. REGISTRATION: PROSPERO CRD42024551180.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
