Ordinal logistic regression results for discharge AIS (number of observations = 489).

R-Square = 0.6637,Max-rescaled R-Square = 0.7156.Dependent variable: AIS at Discharge (A, B, C, D, E).Independent variables: AIS at Admission (A, B, C, D), Neurological Level (High, Medium, Low), Rehabilitation (Yes, No) AIS: American Spinal Injury Association (ASIA) Impairment Scale DF: degrees of freedom.The Wald Chi-Square test is used to test the statistical significance of parameters in the logistic regression models.
