Odds ratios (95% CI) and p-values for the presence/absence of LD cases in a census subdivision (CSD) as a function of individual predictors, including social-behavioral risk factors (either GK and GRP or GPB only), predicted tick density, and population density (model 1A–1C) or as a function of social-behavioral vulnerability index (model 2A) and prioritization index (model 2B).
