Figure 3

Location of the 629 bovine spongiform encephalopathy (BSE) cases under study (A) and disease mapping of the relative risk for BSE compared with the average national risk (B). For improved legibility, map B was smoothed using a spatial interpolation of the relative risk for BSE in the delivery areas.
