NOTE: To evaluate differences at T2 and T3, longitudinal mixed-effects regression models were used that controlled for baseline outcome values. All regression models were adjusted for age in years and gender.

Abbreviation: RR, relative risk.

  • aIndicates significant differences.

  • bFor continuous outcomes, differences shown are age- and gender-adjusted estimates of the change in FOBT (+) group minus the change in the FOBT (−) group.
