What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

Breast cancer is the most common cancer among women in Singapore, yet only 30-40% attend regular mammograms. This trial enrolls 12,000 women aged 50-69 who haven't had a mammogram in two years. It compares five approaches: a simple reminder, a $10 voucher, a chance to win $5,000, a video from an influential person, and a personal concierge to schedule the appointment. The goal is to find which strategy works best to increase screening and, ultimately, save lives.

What this could mean

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

What this could lead to
If successful, this study could identify simple, scalable ways to double or triple mammography participation, potentially reducing breast cancer deaths in Singapore and across Asia.
What could go wrong
The trial tests behavioral nudges, not a medical treatment, so even if uptake rises, it may not translate into lower mortality. Results depend on cultural context and may not generalize outside Singapore.
