Notes: Coefficients reported in odd ratios; each row represents a full interaction model of which only the coefficients for the terms involved in the interaction are shown; CCI = coefficient of climate change index; IntMig = coefficient of community-level international migration prevalence; CCI × IntMig = coefficient of interaction term between CCI and IntMig; one unit reflects a 10% change in international migrant prevalence; variables were centered;
