  • Multivariate Poisson regression analysis assessing the incidence rate ratio of missed dialysis as a function of independent patient characteristics. For dialysis-specific preparedness and age, incidence rate ratio was calculated as a function of numeric variants. Ethnicity, supplemental hemodialysis facilities, evacuation, and living situations were analyzed as categorical (or binary) data. The control group is shown in parentheses. For example, white is associated with 33% lower incidence rate ratio compared with black.
