  Healthy individuals Individuals with mild/moderate dysplasia Individuals with severe dysplasia Individuals with carcinomas
Total number of individuals in the study (n = 18) (n = 87) (n = 13 ) (n = 121)
Number of men 6 61 7 66
Number of women 12 26 6 55
Mean age ± S.D. 56.8 ± 4.5 56.9 ± 3.6 54.9 ± 3.1 69.5 ± 12.0
  1. Comparing the group of healthy individuals with the other groups showed that there were significantly more males in the group with mild dysplasia and CRC (p < 0.001; Chi Squared test). The mean age is significantly higher among patients with CRC compared to the three other groups (p < 0.001; Kruskal-Wallis and Dunn's Multiple Comparison test).
