Machine learning shows promise for spinal cord injury (SCI) prognosis but faces challenges. Current models suffer from incomplete reporting, high bias, and limited external validation, hindering clinical use.

Area of Science:

  • Medical Informatics
  • Neurology
  • Biostatistics

Background:

  • Machine learning (ML) is increasingly utilized for prognostic prediction models in spinal cord injury (SCI).
  • Existing SCI prognostic models exhibit significant heterogeneity in outcome measures, predictors, modeling strategies, and validation methods.
  • Systematic evaluation of reporting quality, risk of bias, and clinical applicability of these ML models is lacking.

Purpose of the Study:

  • To assess the reporting quality and risk of bias of ML-based prognostic models for SCI.
  • To evaluate the clinical applicability, model features, validation, and implementation barriers of these models.

Main Methods:

  • A comprehensive literature search was conducted across multiple databases up to May 14, 2025.
  • Two independent investigators screened studies, extracted data, and assessed risk of bias.

  • The Transparent Reporting of a Multivariable Prediction Model for Individual Prognosis or Diagnosis (TRIPOD) statement and the Prediction Model Risk of Bias Assessment Tool (PROBAST) were used for evaluation.

    • Main Results:

    • Nineteen cohort studies were included, with TRIPOD adherence ranging from 54.8% to 81.1%.
    • All 19 studies exhibited a high risk of bias, primarily due to analytical limitations.
    • External validation was present in only one study; most relied on internal validation or model development only, with issues in sample size justification, missing data handling, and calibration.

    Conclusions:

    • ML holds potential for SCI prognostic modeling, particularly with complex data.
    • However, current evidence is hampered by incomplete reporting, high risk of bias, heterogeneity, and insufficient external validation.
    • Robust, larger studies with standardized outcomes and external validation are essential for clinical implementation.
