Summary

This study aimed to create a web-based decision aid for people invited to cancer screening in Sweden. The tool would provide clear information about the benefits and harms of screening, helping individuals decide based on knowledge rather than fear. The study was withdrawn before it started, so no results are available.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Individual decision aid (iDA) - a web-based tool
What this could lead to
If successful, this could help people make more informed, personal decisions about cancer screening, potentially increasing participation and reducing fear or misconceptions.
What could go wrong
The study was withdrawn before enrolling any participants, so no data was collected. The tool may not work as intended or may not reach the groups that need it most.
