Risk of colon cancer in hereditary non-polyposis colorectal cancer patients as predicted by fuzzy modeling: Influence of smoking

Figure 3 Scattergram demonstrating the probability of developing CRC (cumulative lifetime risk) for each subject based on genetic mutation, ◊ = hMLH1, ● = hMSH2. Data are divided by sex and smoking status with (A) Female: non-smokers (P < 0.001), (B) Female: smokers (P < 0.001), (C) Male: non-smokers (P < 0.001) and (D) Male: smokers (P < 0.05). The P values show the probability failing to reject the null hypothesis that the data originate from identical populations, indicating that the curves are different.
