Trial Outcomes & Findings for A Smartphone-Based Intervention to Improve Colorectal Cancer Screening in African American Men (NCT NCT06052202)
NCT ID: NCT06052202
Last Updated: 2026-01-02
Results Overview
This measure assesses whether or not a participant received a colorectal cancer screening test since beginning the study. The date and type of screening will be verified via electronic health records. A value of "0" will be recorded if no screening test is found in the electronic health record. A value of "1" will be recorded if a screening test is found in the electronic health record. The percentage of participants with a electronic health record verified screening will be calculated from these values.
