Fig. 3.

Median correlation between posterior samples of cancer types in the Morecambe Bay ex CCG extended area. Orange = no correlation; green = negative correlation (areas with high incidence in one cancer type have low incidence in the other cancer type); and red = positive correlation (both cancer types have high incidence in the same area). The correlation threshold is arbitrary: negative correlation is lower than −0.3; positive correlation is above 0.3 and no correlation (or weak correlation) is between −0.3 and 0.3.
