  1. *The statistical different among slice thicknesses was made using Kruskal–Wallis test
  2. The statistical different between male and female was made using Mann-Whitney test
  3. αThe correlations between Detection score and Lymph node width, Body weight, Body condition score or Degree of obesity were made using Spearman correlation
