Impact of the randomization procedure (random swapping versus spatially ordered swapping of indicators of late-stage diagnosis) on the results of the test of hypothesis. The number of incidence rates in the contingency table of Figure 2A that are declared significantly larger or smaller than the tri-county average of 18% are reported for α=0.05 and three types of multiple testing correction: No correction, False discovery rate (FDR) correction, and simulation-based procedure (JEF).
