RC A: Qualifying LACT results. Rows, from the top, represent the LACTs (Episcan, FleXScan, and SaTScan areal) and 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.
