Unbiased Recursive Partitioning to Stratify Patients with Acute Traumatic Spinal Cord Injuries: External Validity in an Observational Cohort Study.

We found that one of the four predictor variables failed to reach statistical significance in our independent sample (Node 4: Motor ZPP, n = 36; Table 2 ), one of the stratified groups did not fit a sequence of progressively improving UEMS scores (Node 6), and three of the five stratified groups had medians that were not statistically significantly different from their adjacent medians ( Table 3 ).
