headline: Functional outcome prediction after traumatic cervical spinal cord injury using ensemble machine learning: a three‑center validation study
dek: Background Traumatic cervical spinal cord injury (TCSCI) often causes severe neurological dysfunction. Accurate prediction of functional recovery is essential for clinical decision‑making and rehabilitation planning. Objective To develop an ensemble learning model integrating baseline clinical data, neurological assessments, and cervical MRI features to predict neurological recovery and functional outcomes at one year post‑injury in TCSCI patients. Methods We retrospectively collected data from 410 TCSCI patient…
gain_title: An ensemble Stacking model using baseline clinical, neurological, and MRI features predicted one-year AIS grade and motor/independence scores in TCSCI patients with high discrimination and low error on external testing.

gain_reading: An ensemble Stacking model using baseline clinical, neurological, and MRI features predicted one-year AIS grade and motor/independence scores in TCSCI patients with high discrimination and low error on external testing.
gain_evidence: The model achieved AUC 	 0.85 for all AIS grades. | This externally validated model accurately predicts 1year functional recovery in TCSCI patients and may support early prognosis assessment and individualized rehabilitation planning.

quick_read: By August 2026, researchers had developed and externally validated a two-layer Stacking ensemble that integrates baseline clinical data, neurological assessments, and cervical MRI features to predict one-year outcomes after traumatic cervical spinal cord injury. In 340 patients analyzed, the model predicted AIS grade with AUC 	 0.85 and predicted continuous motor and independence scores with R8 above 0.986.

Accurate early prognosis could help clinicians counsel patients and tailor rehabilitation plans, but the evidence is retrospective and limited to three centers and 98 external test patients. Prospective validation, broader populations, and assessment of impact on actual clinical decisions remain needed before routine use.

tag: Evidence-backed gain
key_points: Retrospective study of 410 TCSCI patients from three institutions (2017-2025), with 340 analyzed: 242 training and 98 external test set. | Two-layer Stacking ensemble integrated demographic, clinical, and radiologic features including maximum spinal cord compression. | Primary outcome was one-year ASIA Impairment Scale grade; secondary outcomes were UEMS, LEMS, TMS, and SCIM III.
rundown: Researchers collected baseline demographic, clinical, and cervical MRI features from patients across three centers between 2017-2025 and built a two-layer Stacking ensemble. Performance was assessed with AUC-ROC, R8, MAE, and RMSE, and SHAP analysis was used to quantify predictor contributions.

On the 98-patient external test set, the model maintained AUC 	 0.85 for all AIS grades and achieved low MAEs of 2.0667 for UEMS and 3.5956 for SCIM III. SHAP identified baseline UEMS and AIS grade as most influential, followed by maximum spinal cord compression (MSCC).
