Development and validation of an MRI-Based nomogram for predicting neurological recovery after acute cervical spinal cord injury.
Article in Spinal cord, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
STUDY
designRetrospective cohort study.
objectivesAcute cervical spinal cord injury (CSCI) leads to severe and variable neurological outcomes. Early, accurate prognosis is crucial for clinical decisions and patient counseling. This study aimed to identify key prognostic factors and develop a reliable, imaging-based nomogram for predicting neurological recovery after surgical treatment.
settingNorthern Jiangsu People's Hospital Affiliated to Yangzhou University, Yangzhou, Jiangsu, China.
methodsIn a retrospective cohort of 103 surgically treated acute traumatic CSCI patients, neurological recovery was defined as ≥1 grade improvement on the ASIA Impairment Scale at 6 months. We analyzed clinical variables and MRI parameters: intramedullary edema length (IEL), intramedullary hemorrhage length (IHL), and maximum spinal cord compression (MSCC). Independent predictors were identified via multivariate logistic regression. A nomogram was built and internally validated using the C-index, calibration curves, ROC analysis, and DCA.
resultsNeurological recovery occurred in 73 patients (70.9%). Multivariate analysis identified IEL (OR = 0.904), IHL (OR = 0.808), and MSCC (OR = 0.812) as independent predictors (all p < 0.05). IEL showed a threshold effect at 48 mm, beyond which recovery probability declined markedly. The nomogram demonstrated excellent predictive performance, with C-indices of 0.969 (modeling) and 0.936 (validation). ROC and DCA confirmed its superior accuracy and clinical utility over single parameters.
conclusionsIEL, IHL, and MSCC are key imaging-based predictors of recovery after acute CSCI. The developed nomogram provides an accurate, practical tool for individualized prognosis, supporting precision clinical management. MRI-based parameters including intramedullary edema length (IEL), intramedullary hemorrhage length (IHL), and maximum spinal cord compression (MSCC) were integrated into a nomogram model to predict neurological recovery in patients with acute cervical spinal cord injury.
