- Scan-c: circular scan method, Scan-e 0: standard elliptic scan method, FleX: unrestricted flexible scan method, GA-1: strongly penalized genetic algorithm, Double and Mlink: dynamic minimum spanning tree method with double and maximum link connections, respectively. No. LZ: size of living zones in the cluster (number of living zones); RR: relative risk in the true cluster. Results based on 250 Monte Carlo replications.
- 1 "small", "moderate" and "large" clusters are clusters with about 20, 45 and 115 cases of childhood acute leukemia over the period 1990-2006, respectively.
