    Note:—WD indicates well-defined; mild, <30% of an affected lymph node; moderate, 30%–70% of an affected lymph node; severe, >70% of an affected lymph node.
  • 


    ↵a Unless otherwise indicated, data are expressed as the number of patients, with percentages in parentheses.
  • 


    ↵b Calculated with the Fisher exact test. The other categoric variables were compared using the χ2 test.
  • 


    ↵c CTN of >44.5 HU is used as the threshold for differentiating KD from TL.
  • 


    ↵d CTN/M of >0.7 is used as the threshold for differentiating KD from TL.
