A map matrix displaying eight SaTScan runs for cervical cancer. The eight runs increase the maximum-size parameter systematically (4%, 6%, 8%, 10%, 20%, 30%, 40%, and 50%). As the maximum-size parameter is increased, the clusters reported by SaTScan vary in both location and size (as illustrated by the growing black circles and gray circles). For illustration purposes, we carefully draw circles around the boundary of the clusters. For each result, the primary cluster is in a black circle; and some secondary clusters are in gray circles.
