About ME/CFS Atlas

About

ME/CFS Atlas was created from a simple conviction: people living with ME/CFS deserve better knowledge infrastructure.

The field is complex. The evidence is uneven. The language is often imprecise. For many people trying to understand ME/CFS, the burden of searching through fragmented information can become almost as difficult as the uncertainty they are trying to navigate.

This project is an attempt to build something more exact.

The atlas is designed as an open, structured knowledge atlas — and as a practical tool for navigating a complex field — for people who need clarity and for people who need to find something specific. Its purpose is not to flatten the illness into slogans, and not to pretend that science is more settled than it is. Its purpose is to make the field more legible, more navigable, and more intellectually honest.

The atlas gathers, structures, and classifies research — making evidence levels visible, distinguishing observed findings from inferred conclusions, and flagging what remains uncertain. Its navigation and filtering system is designed to help readers move from a large corpus to a smaller, more relevant set: by disease context, symptom domain, biomarker type, phenotype, study design, PEM status, and methodological quality. It is built for patients, families, clinicians, and researchers, but above all for people who need a place where seriousness, precision, and care can coexist.

The project was initiated by an independent founder working from close, long-term engagement with the realities of ME/CFS and from a strong commitment to clarity, structure, and scientific seriousness. The project is intentionally not built around personal visibility. It is built around a task: to make knowledge more accessible without making it shallow, and more supportive without losing intellectual discipline.

The atlas is, however, an informational and educational platform only. It is not a medical service, diagnostic instrument, treatment provider, or substitute for professional medical advice, diagnosis, or care. Its content is intended to support public understanding, not to replace clinical judgment or individualized decision-making.

Every effort is made to present research and evidence carefully, transparently, and in good faith. But no system of this kind is free from limitation. Science evolves. Evidence changes. Interpretation remains imperfect. Software may contain bugs. Data pipelines may introduce omissions, labeling errors, or outdated material. Automated and semi-automated systems may occasionally summarize imperfectly, classify incompletely, or fail to capture the full nuance of a paper.

For that reason, the platform should be used with appropriate caution and independent judgment. Use of the site, its summaries, classifications, tools, and future chatbot features is at the user's own discretion and risk.


Manifesto

We believe that people with ME/CFS deserve better than fragmented information, overstated claims, and systems that are difficult to trust.

They deserve structure.
They deserve clarity.
They deserve honesty about what is known, what is emerging, and what remains unresolved.

This atlas exists to help build that clarity.

We do not believe that more information automatically leads to better understanding. In fields marked by complexity, disagreement, and uneven evidence, what matters is not only access, but structure. Not only volume, but judgment. Not only visibility, but method.

This project is built on a few simple principles.

Evidence should be legible.
Weak evidence should not look strong.
Promising signals should not be exaggerated.
Uncertainty should not be hidden.
And what is central to the illness should not be treated as peripheral.

For ME/CFS, that means post-exertional malaise must be taken seriously as a defining feature, not reduced to a footnote or blurred into generic fatigue. It means differences in study quality, case definitions, phenotyping, and severity must matter. It means the public deserves access not only to findings, but to the structure of those findings, how they are classified, how they are limited, and why they are interpreted the way they are.

We also believe that design is not cosmetic. For people living with limited energy, clarity is not a luxury. It is part of access. Calm design, readable structure, and low cognitive load are not aesthetic afterthoughts. They are ethical choices.

This is why the atlas aims to be more than a website. It aims to become a durable public knowledge surface, a place where research can be explored without distortion, where evidence can be understood without simplification, and where people can orient themselves without being overwhelmed.

The ambition is not to present itself as a final authority. Science does not work that way, and neither should a project like this. The ambition is more disciplined than that: to create a serious, transparent, and humane atlas of the field, one that helps people see more clearly what is established, what is suggestive, what is contested, and what still lies beyond current knowledge.

That same discipline requires humility. The presence of a study, summary, topic page, evidence label, or chatbot answer on this platform does not make it final, exhaustive, or universally applicable. Evidence may later be revised. Interpretations may change. Reasonable experts may disagree. Software-assisted systems may fail. Human review may still miss something. No platform of this kind can guarantee perfect completeness, correctness, or freedom from error.

What we do not know should not be concealed.
What we do know should not be diluted.
What is hopeful should not be inflated.
What is weak should not be polished into certainty.

If this project succeeds, it will not be because it claimed too much. It will be because it made complexity more readable, made uncertainty more honest, and made the landscape of ME/CFS easier to navigate for the people who need that most.


How the Atlas Works

Evidence Levels

Every study in the atlas is assigned an evidence level based on study type and replication status, not on whether the findings are encouraging or discouraging.

E0 Consensus

Major reviews, guidelines, evidence maps, and foundational syntheses.

E1 Replicated

Replicated human evidence from multiple independent studies.

E2 Moderate

Single-study or moderate support from human research.

E3 Preliminary

Early hypothesis, preprint, editorial, or weak support.

Evidence level is not a quality guarantee. E0–E3 reflects study type and replication status, not the methodological rigour of an individual paper. A systematic review with weak methods — or built on a weak or biased set of primary studies — still sits at E0. Reviews and guidelines in ME/CFS have historically included both strong work and work patients and independent researchers have criticised on methodological grounds. The level tells you how the evidence is structured; it does not replace reading the case definition, methods, and limitations of the study itself.

Review Process

Studies enter the atlas through a structured pipeline. Each record is ingested, deduplicated, normalized, classified, and summarized before it becomes visible. Every study carries a review status label so you always know how it was processed.

Machine draft

Classified and summarized by AI. Not yet human-reviewed.

Editor reviewed

Reviewed by an editor for accuracy, classification, and summary quality.

Expert reviewed

Reviewed by a domain expert for clinical and scientific accuracy.

AI Transparency

The atlas uses AI to assist with classifying studies, generating plain-language summaries, and identifying relevant tags. All AI-generated content is labeled as “Machine draft” until reviewed by a human editor. AI is a tool for scale, not a substitute for judgment. Every classification, summary, and label can be corrected, relabeled, or revised through the editorial process.

What Every Study Page Shows

Each study in the atlas is structured to help you assess the evidence for yourself. Every study page includes:

  • What was observed (findings)
  • What is inferred (conclusions)
  • What remains unknown (open questions)
  • What it does not prove (limitations)
  • Evidence level and confidence
  • PEM status and case definition
  • Publication type and peer-review status
  • Review state and methodology notes

Navigating the Evidence

The Evidence Atlas is designed not only to be read, but to provide a structured way to explore the corpus. Rather than presenting a flat list of studies, it is organized around filter dimensions that reflect the clinical and methodological specifics of ME/CFS research.

From the Evidence page, you can filter by:

  • Evidence level — E0 (consensus) through E3 (preliminary)
  • Disease context — ME/CFS, Long COVID, post-infectious, overlapping
  • PEM status — whether post-exertional malaise was required in the case definition
  • Symptom domain — PEM, cognitive dysfunction, pain, unrefreshing sleep, orthostatic intolerance, and others
  • Biomarker type — cytokines, gene expression, metabolomics, neuroimaging, autoantibodies
  • Phenotype — infection-triggered, pediatric, severe, Long COVID overlap
  • Method quality — strong phenotyping, sex-stratified analysis, inclusion of severe ME
  • Study design — systematic review, meta-analysis, RCT, case-control, observational, and more
  • Confidence and peer-review status

Combining filters helps narrow the corpus to a smaller and more relevant set of studies. Search and sort are available alongside filters, and filter state is preserved in the URL so that a filtered view can be shared or bookmarked.

Public Atlas vs. Internal Corpus

The atlas maintains a large internal research corpus drawn from PubMed and other sources. Only studies that pass quality checks and moderation are published to the public atlas. The number of studies you see on the site reflects the curated public collection, not the size of the raw corpus. This distinction is intentional: trust and quality matter more than volume.


ME/CFS Atlas is an evidence reference platform, not a medical provider. Content is for informational purposes only and does not constitute medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional for medical decisions. Use of this platform, its summaries, classifications, and tools is at your own discretion and risk.
