Radiologic grading scores enhance clinical model's prognostic ability for Guillain-Barre syndrome.

ABSTRACT:

Objective

To assess the value of magnetic resonance imaging (MRI) grading scores based on lumbosacral muscle denervation edema in predicting the course of Guillain-Barré syndrome (GBS).

Methods

We collected data from 354 GBS patients and developed MRI grading criteria (5-point scale) based on the transverse area and longitudinal length of lumbosacral edema. Univariate and multivariate logistic regression analyses were conducted to identify factors associated with GBS prognosis among 12 demographic and radiological features. Clinical models and clinical-MRI models were separately trained and validated by data from Institution 1. External test was performed using data from Institution 2. Differences between the models were assessed using the z-test.
