Figure 2

Results of unadjusted space-time cluster analyses performed in SpaceStat. Analyses were carried out with 999 permutations, k =25 and 100. 2a shows cluster areas detected at k = 25 in the Odense (inserted map) and Copenhagen areas with each of the two control groups as well as when control groups were combined. 2b shows cluster areas detected at k = 100 with each of the two control groups and the combined control group. The cluster areas presented in the figures illustrate the maximum extent of the cluster areas based on the location of significant cases, and the colours of the areas indicate the control group used. This presentation of results secures the anonymity of the study participants (in contrast to presenting the actual address points on the maps). For each cluster area the text box show how many cases it comprised and its temporal extent. CG: Control Group.
