Continuous variables are presented as mean ± SD and categorical variables as N (%). *Data provided includes the full sample of participants (n = 37) except for AIS classification (n = 36). American Spinal Injury Association Impairment Scale (AIS), International Spinal Cord Injury Pain Basic Dataset (ISCIPBDS). Associations of participant characteristics with worst neuropathic and nociceptive pain intensities rated on the ISCIPBDS are reported from Kendall’s Tau (τ) for continuous variables and Wilcoxon Rank-Sum (W) or Kruskal-Wallis (H) tests for categorical variables.
