CI, confidence interval; FIT, fecal immunochemical test; OR, odds ratio.

Combined July and October 2018 mailings; participants also received automated phone call and live phone calls delivered at discretion of care team.

Adjusted for clinic and mailing month (July vs October).

Included patients reached by text message or phone call (left message or spoke to patient).
