3.2.1. Models Predicting Non-Institutional Case Incidence
Variables associated with non-institutional cases are shown in Figure 2 (left points in lighter green). As with the models of all cases, consistently significant positive associations in both Phase 1 and Phase 2 included proportions of Black and Latinx residents, essential services workers, and those without health insurance. Proportion of undergraduate students was the only consistently significant negative association for non-institutional cases. Substantive attenuations toward the null between Phases 1 and 2 were exhibited in % Black (decreasing from 1.22 [1.18, 1.25] to 1.03 [1.01, 1.05]), % Latinx (decreasing from 1.36 [1.31, 1.42] to 1.13 [1.11, 1.16]), and % undergraduates (increasing from 0.83 [0.80, 0.86] to 0.93 [0.91, 0.94]). LTCF beds per capita, population proportions of AIAN residents, housing density, and share of individuals aged over 80 years were not significant predictors of non-institutional cases.
