Alternative approaches to assessing intervention effectiveness in randomized trials: application in a colorectal cancer screening study

摘要

Background Previous analysis of a randomized community-based trial of a multi-component intervention to increase colorectal cancer (CRC) screening among Filipino Americans (n = 548) found significantly higher screening rates in the two intervention groups compared to the control group, when using intent-to-treat analysis and self-reported screening as the outcome. This report describes more nuanced findings obtained from alternative approaches to assessing intervention effectiveness to inform future intervention implementation.
