NA=No results obtained because the software did not converge due to missing values.
Frankel A: lesion was found to be complete, both motor and sensory, below the segmental level marked.
Frankel B: some sensation present below the level of lesion but the motor paralysis was complete below that level
Frankel C: motor power present below the lesion but it was of no practical use to the patient
Frankel D: useful motor power below the level of the lesion.
Frankel E: the patient was free of neurological symptoms
