Superscripts to adjusted odds ratios indicate presence of reversed associations (RA1, RA2) and/or large percent changes (LPC) to the unadjusted ORs.
RA1: Unadjusted OR statistically significantly lower than Whites; adjusted OR statistically significant, higher estimated screening rate compared to Whites.
RA2: Unadjusted OR not significantly different from Whites; adjusted OR statistically significant, higher estimated screening rate compared to Whites.
LPC: The multivariable, fully-adjusted change from the unadjusted OR is 50% or more.
Analysis sample sizes are shown in the box with each survey year. Analyses incorporated adjustments for sampling.
