Notes:

^aLCL=Bonferroni-corrected Lower Confidence Limit.

^bUCL= Bonferroni-corrected Upper Confidence Limit. Bold-faced numbers indicates statistical significance with p-value<0.05.

^cAdjusted p-values are based on Bonferroni correction.

^dAge Groups: 1:18–34; 2:35–44; 3:45–54; 2#2 means interaction of age group 2 and race quintile 2, and so on.
