Summary

This study tests whether sending a single SMS reminder to people who haven't completed a colorectal cancer screening test can increase participation. Over 10,000 adults aged 50-69 in Spain will be randomly assigned to receive either the SMS or standard postal reminders. The goal is to see if a simple text can help meet the recommended 65% screening target.

What this could mean

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

Active substance
SMS text message reminder
What this could lead to
If it works, this could show that a simple text message can significantly increase colorectal cancer screening rates, helping catch cancer earlier.
What could go wrong
This is a behavioral study, not a medical treatment. The effect may be small or not apply to other regions. It only measures participation, not cancer outcomes.

The number the study aims to enrol. It can still change while the study runs.

Started

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
