3.3. Comparisons between Total and Non-Institutional Cases and
Deaths
We observed some similarities and differences in predictors between the
models for total cases and deaths and for non-institutional cases and
deaths (Table 2). Most notably, the strongly positive associations
between LTCF beds per capita and total cases and deaths were sharply
reduced to statistical non-significance in the non-institutional models,
per our original hypotheses. All other variables had confidence
intervals that overlapped between the total and non-institutional
models, and estimates were similar across all remaining variables in
both phases between total and non-institutional cases. However, a few
substantive differences emerged in the IRR point estimates from models
with total versus non-institutional deaths, albeit confidence levels
overlapped. Associations between % Black, % Latinx, % aged over 80
years, and % essential workers and non-institutional deaths were
greater than the associations with total deaths across both phases. The
largest absolute difference was for the % Black variable in Phase 1
deaths, which was 1.20 (1.11, 1.30) for total deaths and 1.32 (1.23,
1.41) for non-institutional deaths.
