Data are expressed as group mean (SD). AB able-bodied, SCI spinal cord injury, Normal: HDL-C >40 mg/dl; Low: HDL-C ≤40 mg/dl; BMI body mass index, AIS American Spinal Injury Association Impairment Scale, DOI duration of injury. P-values represent significant group main effects. Significant comparisons from post-hoc analyses: 1AB –Normal v. SCI-Low = p < 0.05
