Predictors included UEMS at week 1\/week 4 and American Spinal Injury Association Impairment Scale (AIS) category. Ordinal regression models to predict UEMS at 4, 12, 24, and 48\u2009weeks were developed and internally validated using bootstrap-based stability plots. External validation of the 12-week model was performed using a North American cohort of 365 patients.
