From: Geospatial analyses identify regional hot spots of diffuse gastric cancer in rural Central America
Spatial clustering of diffuse type gastric cancer, Getis Ord Gi* hot spot cluster analysis. Spatial clustering of diffuse gastric cancer incident cases were identified by two independent GIS methodologies. The Getis Ord Gi* hot spot analysis (Fig. 1), identified three neighboring hotspots in western Honduras that may be considered one cluster area (P value < 0.0015; range 0.00003–0.0014; 99% CI). The spatial scan statistic SaTScan (not shown) also demonstrated a statistically significant cluster (32 km radius) in the same location (P-value < 0.006; range 0.0026–0.0054). The intestinal subtype cancers were randomly distributed, and without high incidence clusters
