  1. The radius is reported only when the cluster areas include more than one unit and the criteria for Reporting Secondary Clusters is “no geographical overlap." As for the cluster type, "1" represents "Most likely cluster"; "2" represents "Secondary cluster." The results scanned by elliptic scanning window can be found in the Additional file 4: Table S4
