  2. aEndoscopy screening is defined as having ever had either sigmoidoscopy and colonoscopy and reporting receipt of any of these screening tests in the past year. bAdjusted prevalences are predicted marginals derived from multivariate logistic models predicting endoscopy use, that adjusted for covariates listed above, in addition to state fixed effects.
