Figure 3From: Detection of clusters of a rare disease over a large territory: performance of cluster detection methodsThe 9 clusters under study (3 cluster shapes and 3 cluster locations). The nine scenarios considered consisted in a combination of 3 cluster shapes (linear, U-shaped and compact) and 3 locations equivalent to 3 population sizes (20 expected cases for clusters 1-3,45 expected cases for clusters 4-6 and 115 expected cases for clusters 7-9).Back to article page
