Decision tree of the SVM_linear model trained with the “Lab + ISNCSCI + K-MBI + FIM” dataset of DKUH to classify the non-PU and PU groups. The “ambulation” subscale of the K-MBI was identified as the first single discriminator for determination of the two groups. The red line indicates “yes”, and the blue line indicates “no”. Abbreviations: K-MBI = Korean version of the Modified Barthel Index; ISNCSCI = International Standards for Neurological Classification of Spinal Cord Injury; FIM = Functional Independence Measure; LER = lower extremity, right; UER = upper extremity, right; AIS = ASIA Impairment Scale; LTL = light touch, left; LEL = lower extremity, left; PPL = pinprick, left; UEMS = Upper Extremity Motor Subscore; LT, total = light touch, total, MCH = mean corpuscular hemoglobin; MCHC = mean corpuscular hemoglobin concentration.
