Fig. 5From: Spatial-temporal epidemiology of human Salmonella Enteritidis infections with major phage types (PTs 1, 4, 5b, 8, 13, and 13a) in Ontario, Canada, 2008–2009Spatial clusters of Salmonella Enteritidis cases with major phage types in Ontario, Canada, 2008–2009. Results based on discrete Poisson models using the SaTScan™ software. Study period: January 1, 2008 to December 31, 2009. Circular scanning window size: up to 50 % of the population at risk. Confounders controlled for: age (0–9, 10–24, 25–34, 35–49, ≥ 50 years) and sex. Criteria for reporting secondary clusters: no geographical overlap. Type of clusters investigated: high rate only. RR = relative risk. Significance level: p ≤ 0.05Back to article page
