PREDICTOM Study Progress

Welcome to the Study Progress Tracker!

This page provides regularly updated information on the progress of the PREDICTOM study for everyone interested in following its development. The tracker will show progress for both Level 1 and Level 2 as the study advances.

For example, Level 1 includes tasks such as online tests, questionnaires and biofluid samples (blood and saliva test kits). The progress bars display only consent registrations, giving an accurate picture of how close we are to reaching our goals. You can explore the status by country and the overall European progress, which combines data from all seven clinical sites involved in the study: Belgium, France, Germany, Norway, Spain, Switzerland and the United Kingdom.

We share these updates to ensure transparency and to give you a glimpse behind the scenes of research. This includes challenges such as silent participant drop-out, which is a normal part of long-term studies.
