Space-time 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 and 50 % of the study period. Confounders controlled for: age (0–9, 10–24, 25–34, 35–49, ≥ 50 years) and sex. Time aggregation units: month. Time aggregation length: 1 month. Criteria for reporting secondary clusters: no geographical overlap. Type of clusters investigated: high rate only. RR = relative risk. Significance level: p ≤ 0.05
