Figure 1. Flow of Participants Through the Study.

Figure 1

FIT indicates fecal immunochemical test.

aOverall 19 514 individuals were assessed for eligibility and 6000 were selected for randomization. One individual was randomized twice to the usual care group due to multiple medical record numbers; therefore, the individual was excluded from the Figure.

bPer a priori power calculations, the target sample size was 6000 individuals. A random sample of 6000 individuals was taken from the eligible population (n = 8740); therefore, 2740 individuals were not selected for randomization.

cLost to follow-up was defined as a lack of subsequent visits at Parkland Health and Hospital System (Dallas, Texas).
