  1. For each cluster area, the “x” indicates in which analyses the cluster was detected according to method, number of cases, adjustment, time scale, choice of a k-nearest neighbours and by control group b1, c2 and d1 & 2 combined. eOnly borderline significant. For selected analyses the cluster areas are depicted in the figures listed in the last column.
