Table 6 Pearson correlation between age (years), time since injury (hours), and FA at the level of injury

From: Magnetic resonance diffusion tensor imaging of acute spinal cord injury in spinal trauma

  Age (years) Time since injury (hours)
r p value R p value
FA value at site of injury − 0.148 0.436 − 0.210 0.266
  1. r: Pearson’s correlation
  2. p value: probability for independent samples t test for association between patients and control group
