A procedure to characterize geographic distributions of rare disorders in cohorts-2

columns, from the left, represent the areal unit sets (Set 1 (maximum unit pop. = 1000), Set 2 (maximum unit pop. = 2000). The underlying green and blue points indicate the qualifying SaTScan point clusters. All other located births are gray points. On Row 1, the Episcan display uses a heat map to indicate the most likely cluster area within reported significant clusters. In Row 3, Column1, SaTScan areal Set 1 had two overlapping significant clusters, both shown here in different colors.Copyright information:Taken from "A procedure to characterize geographic distributions of rare disorders in cohorts"http://www.ij-healthgeographics.com/content/7/1/26International Journal of Health Geographics 2008;7():26-26.Published online 28 May 2008PMCID:PMC2430550.
