  1. *RR = The relative risk of being a human case or a broiler case within a space-time cluster compared to outside.
  2. #muni. = municipalities, Hu = human, Br = broiler
  3. Characteristics of simultaneous space-time clusters of human campylobacteriosis and broiler flocks positive for Campylobacter spp. identified by the multivariate SaTScanâ„¢ Poisson model. The clusters are ranked according to their likelihood ratio test statistic.
