aRR = Adjusted estimate of relative risk of being unscreened. For individual-level patient attributes, values are shown for models that did not include census tract attributes; aRR values for these attributes were similar in all models that included census tract attributes, and aRR values with confidence intervals that exclude 1.0 were the same.
P < .05 for contingency table with 2 to 4 rows (depending on variable) and 2 columns (screened versus unscreened).
P < .05, 2-tailed.
These measures describe attributes of the population in each patient’s census tract of residence. Categories are terciles for all measures, except for racial segregation index. Tercile boundaries for census tract attributes might appear to overlap because of rounding.
A z score of >1.96 indicates significant racial segregation in census tract where patient resides.
