  1. Models B and C included only the 8 neighboring groups and excluded ties within the same social group. UDOI and intergroup encounter rate were z-transformed. Significant P values (<0.05) are printed in italics
  2. aThe odds ratio is the multiplicative increase in the odds of E. coli strain sharing with each unit increase in the explanatory variable
