Real World Evidence Initiative

Patients' own experience is an essential data source for research.

Anyone living with Long Covid or ME/CFS builds up their own insights over the years into what helps and what doesn't. In research terms, this kind of information is called Real World Evidence. We are the first to capture it systematically for Europe and to report on the results.

Why we do this

A wealth of data that has never been captured systematically.

Anyone who has lived with Long Covid or ME/CFS for a long time has usually tried a dozen therapies and observed which ones changed something and which didn't. Looked at individually, it's hard to draw conclusions for other patients from this. Aggregated, that can be different. But so far these observations remain scattered across support groups, consultations, or private notebooks.

Controlled clinical trials remain the standard for proving efficacy. But Real World Evidence gathers concrete experience from patients' actual day-to-day management of their condition — experience that, in its sheer volume and practical relevance, can offer therapy research a wealth of leads.

On its evidentiary value: our initiative relies on subjective assessments, which cannot match the rigor of data collection in a good clinical trial. The results are not proof of efficacy and not a treatment recommendation.

The model

The approach is already proven in the US.

In 2025, researchers from Harvard Medical School and Stanford University School of Medicine published in PNAS the analysis of the largest patient treatment survey to date. The TREATME study provides an answer, for over 150 therapies, to how often patients reported improvement.

3 925 patients with ME/CFS or Long Covid responded
150+ therapies, medications and measures assessed

The analysis also showed how differently individual patient groups responded to the various therapies. We've compiled the ten therapies with the highest reported improvement rates on our research page: Understanding Long Covid & ME/CFS.

Our REALME study

This initiative brings the methodology to Europe.

European treatment options

Therapies practised in Europe are included here. Therapy options that have only recently emerged can be added on an ongoing basis.

European patients

The characteristics of patients and their subgroups may differ in Europe.

Further data sources

Beyond patient data, we will also bring in further data sources (for example, clinical case studies) to build a comprehensive data basis.

How the survey works

Designed around your needs.

Pacing-friendly

Pausable at any time. You can stop after two minutes and pick it back up days later.

Anonymous

No registration, no real name required. We collect no data that could identify you.

Results for everyone

Result updates for participants, if wanted. The analyses are published openly and free of charge.

Survey content

Disease type & treatment outcomes.

The survey first asks about the form of your Long Covid or ME/CFS. This typing helps us later classify treatment outcomes correctly and possibly identify subgroups ("phenotypes") for which a given therapy would be especially promising.

For treatment experience, we offer you a list of the most common therapy options, but also let you add new forms of therapy.

Take part

Your experience can give practice and research important leads.

You don't need to explain or prove anything to us. Just answer what you yourself have experienced, and leave out the rest.
