Regression coefficients (standard errors) of conditional autoregressive models predicting the annual incidence of campylobacteriosis per 100,000 people in Quebec, Canada, 1996–2006.
^{a} Mean of residuals.
^{b} Pairs of units with population centers within this distance were considered neighbors.
^{c} A similar letter indicates a similar location for the cluster. See Figure 1 for an indication of the exact cluster location.
