Figure 3 Mutation subtypes of each site in gastric mucosa and saliva. (1) “2142G, 2143G and 2144G” indicates the three-sites mutation sub-type; (2) “2142G and 2143G, 2142G and 2144G, 2143G and 2144G” indicate the two-sites mutation subtypes; (3) “Single 2142G, single 2143G and single 2144G” indicate the single-site mutation subtypes; (4) “Total 2142G, total 2143G and total 2144G” indicate the sum of corresponding site mutations in the single-site, two-sites and three-sites mutations.
