  • aP value tested the group effect on the colorectal cancer testing while adjusting for cluster effect (clinic provider).

  • bEleven patients had complicated medical histories for which programming in the CRIS algorithms could not recommend a specific testing regimen; therefore, the final analytical sample for risk-appropriate testing was n = 630.
