We turn scattered evidence into defensible decisions

We bring evidence-based methods into the committees, panels and processes where health decisions actually get made. Clinical epidemiology and study design, evidence synthesis, GRADE guidelines and qualitative research.

Ongoing work with the WHO Methodologist for the WHO iCAM guideline in Geneva. Our CEO also sat on the committee that reviews and approves WHO guidelines, from 2022 to 2026.
We wrote part of the GRADE handbook Co-authors of GRADE Guidelines 19 and 20 and of the GRADE-ADOLOPMENT framework. Our CEO directs the Colombia GRADE Network.
National and international guidelines Guideline methodology for ARIA-EAACI, the American Society of Hematology, the Saudi Ministry of Health and IETS in Colombia.

Why we exist

Information is rarely the problem. Knowing what to trust is.

A clinical recommendation, a coverage decision, an access dossier: each is only as good as the method behind it. Leave that method unwritten and the conclusion falls apart the moment anyone questions it.

We work the other way round: question and analytical framework first, search second. We document every judgement: what went in, what stayed out, with what certainty and why. That trail is what lets you defend your decision to a committee, a peer reviewer or an auditor.

What we do

It all starts with the design

Six capabilities that share a single starting point: the question put properly, and a method able to answer it.

Clinical epidemiology and study design Evidence synthesis and analysis Clinical practice guidelines Qualitative research Health technology assessment and access Training in evidence-based medicine

We automate screening, extraction and literature surveillance. We do not automate the certainty judgement or the interpretation: that stays human, and it goes on the record.

Focus area

Rare diseases

Few patients means thin evidence, and the usual methods fail. That is precisely where methodological judgement decides whether a decision will hold.

In rare diseases you almost never have a large trial, a clean comparator or established outcomes. Follow the standard handbook and you get very low certainty and a paralysed committee. The skill lies in knowing what imperfect evidence will support, and stating the uncertainty openly rather than burying it.

Patient registries, natural history, real-world evidence and formal expert consensus, with the perspective of patients and carers built in through qualitative research.
