  1. NRS, numerical rating scale; pain duration, time to subjective pain relief after treatment began; dV, condylar volume difference between pre- and post-treatment; dV− , net decrease in condyle volume; dV + , net volume increase in condyle.
  2. *, p < 0.05 and **, p < 0.01 in Spearman correlation analysis.
