A-G. Distribution of residuals. Residuals from a CAR model predicting the annual incidence of reported cases of campylobacteriosis per 100,000 people in Quebec (1996–2006) according to various geographical units. Significant clusters (p<0.05) in residuals according to the scan test are illustrated. Classification was done using Jenk’s natural breaks. Dark grey areas represent the unpopulated areas, non-organized territories or incompletely enumerated Indian reserves and settlements within Quebec, whereas light grey shows the frontier area of Quebec.
