Rationale and protocol for a longitudinal cohort study of children with cerebral palsy in China assessing functional developmental trends, genetic aetiology and imaging.

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
introductionCerebral palsy (CP), the most common physical disability in children, imposes substantial economic and psychological burdens on families and society. The clinical management of CP remains challenging due to the limited efficacy of current treatments and the heterogeneity of its aetiologies and clinical presentations. This study aims to investigate the functional changes and identify influencing factors in Chinese children with CP. Through analysis of neuroimaging and genetic data, this study seeks to inform the development of preventive and therapeutic strategies and guide healthcare decision-making for this population. METHODS AND ANALYSIS: This prospective cohort study aims to recruit 2051 children with CP across China. Baseline data will include demographic and clinical characteristics. Participants will undergo comprehensive assessments, including motor, cognitive, language, social, behavioural, nutritional, pain, sleep and quality-of-life domains, with regular follow-up evaluations. Trio whole-exome sequencing and detailed neuroimaging and musculoskeletal imaging will also be performed. This study will also assess caregivers' quality of life and emotional burden. Mendelian randomisation will be adopted to evaluate genetic contributions to functional outcomes and their causal relationship with health metrics. Analytical methods will include correlation analysis, logistic regression (binary and multivariate), linear and non-linear mixed-effects models and structural equation modelling. ETHICS AND DISSEMINATION: Ethics approval was granted by the Research Ethics Committee of Guangzhou Women and Children's Medical Center (No.2023-346A01). All study procedures will adhere to the approved protocol. Study findings will be disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: ChiCTR2300079017.
