Cochrane vs. JBI Methodology: What’s the Real Difference?

Cochrane and the Joanna Briggs Institute, commonly known as JBI, are the two most widely recognized systematic review methodology frameworks internationally. Both are rigorous, both produce reviews recognized as high-quality evidence, and both are frequently requested by name by supervisors, journals, and guideline developers. They are not interchangeable, and choosing between them should be a deliberate methodological decision, not an arbitrary one.

Where each methodology originated and its typical scope

Cochrane originated specifically around intervention effectiveness in healthcare, historically centered on randomized controlled trial evidence synthesized through meta-analysis, though its scope has expanded over time to include diagnostic test accuracy reviews and other review types. JBI originated with a broader scope from the start, explicitly supporting multiple review types beyond intervention effectiveness, including scoping reviews, qualitative evidence synthesis, prevalence and incidence reviews, and mixed-methods reviews, reflecting its roots in evidence-based healthcare and nursing practice more broadly.

This difference in origin still shapes which framework fits a given project. A review narrowly focused on whether a specific drug intervention reduces a specific clinical outcome, drawing primarily on RCT evidence, sits comfortably within Cochrane's traditional strength. A review examining patient experiences of a chronic condition, or mapping evidence across a broad and varied literature, often fits JBI's methodology more naturally, particularly if qualitative or mixed-methods evidence is involved.

Risk-of-bias and appraisal tools

Cochrane reviews of intervention effectiveness use the Cochrane Risk of Bias tool, RoB 2 for randomized trials and ROBINS-I for non-randomized studies, both developed and maintained specifically within the Cochrane methodological ecosystem. JBI maintains its own family of critical appraisal checklists, tailored to different study designs -- separate checklists exist for randomized trials, cohort studies, case-control studies, qualitative research, and several other design types, each reflecting JBI's specific appraisal criteria rather than Cochrane's.

These tools are not directly interchangeable, and a review that states it follows JBI methodology while applying Cochrane's RoB 2 tool (or the reverse) is presenting a methodological inconsistency that a careful reviewer familiar with either framework will notice immediately.

Software and reporting infrastructure

Cochrane reviews are traditionally produced and formatted using RevMan, Cochrane's dedicated review management software, which structures the review according to Cochrane's specific reporting template and handles meta-analysis computation and forest plot generation within the same environment. JBI reviews do not require RevMan and are more commonly written using standard word processing software structured against JBI's own reporting templates, which differ in section structure and required content from Cochrane's format.

Registration and publication pathways

Cochrane reviews intended for publication in the Cochrane Database of Systematic Reviews go through Cochrane's own editorial and peer review process, distinct from standard journal submission, and are registered through Cochrane's own systems rather than PROSPERO in many cases, though this has evolved over time. JBI reviews are commonly published in the JBI Evidence Synthesis journal or other academic journals, and PROSPERO registration is the standard pathway for JBI-methodology reviews intended for broader academic publication.

Which one your project actually needs

If your review question is narrowly focused on intervention effectiveness, draws primarily on quantitative RCT evidence, and you or your institution has a specific expectation or affiliation with the Cochrane framework, Cochrane methodology is the appropriate choice, and following its specific reporting and risk-of-bias conventions throughout is expected. If your review involves qualitative evidence, a scoping or mapping purpose, prevalence estimation, or a mixed-methods design, JBI methodology is generally the better structural fit, given its broader native support for these review types.

A review that borrows selectively from both frameworks -- Cochrane's risk-of-bias tool alongside JBI's broader review-type flexibility, for instance -- is not automatically wrong, but this hybrid approach should be justified explicitly in your methods section rather than presented as if it follows one framework cleanly, since a reviewer trained in either methodology will notice the inconsistency and may read it as a sign of methodological uncertainty rather than deliberate, justified choice.

A practical starting point

If your institution, supervisor, or target journal has not specified a required framework, consider your review type first: intervention effectiveness with quantitative synthesis points toward Cochrane, while qualitative, mixed-methods, scoping, or prevalence-focused reviews point toward JBI. Committing to one framework's conventions consistently, from risk-of-bias tool through reporting structure, is more defensible than mixing conventions from both without explicit justification.

Training and certification differences

Cochrane offers its own structured training pathway, including specific courses on RevMan software and Cochrane's editorial process, often expected or strongly encouraged for reviewers producing work intended for the Cochrane Database of Systematic Reviews specifically. JBI similarly offers its own training program through JBI-affiliated centers internationally, covering its broader suite of review types and appraisal tools. Neither certification is strictly required to conduct a rigorous review following either framework, but institutional or journal expectations sometimes specify one or the other, particularly for reviews intended for formal Cochrane or JBI publication rather than a general academic journal, and worth confirming directly with your target venue and your own institution before committing significant time, tuition fees, or scarce institutional resources to either specific training pathway ahead of a project's actual, confirmed start date -- a decision genuinely worth revisiting periodically as your own review portfolio, methodological interests, and institutional affiliations evolve naturally over the course of a longer academic or professional research career.

A note on terminology consistency

Once you commit to a framework, terminology should follow consistently throughout your manuscript -- Cochrane methodology typically refers to "included studies" and structures its results around comparisons and outcomes in a specific template order, while JBI methodology has its own conventions for structuring findings, particularly for the non-intervention review types it supports. Reviewers trained deeply in one tradition or the other often catch these small inconsistencies within the very first few pages of a manuscript, sometimes before reaching the results at all. A manuscript that shifts between the two frameworks' terminology inconsistently, even if the underlying methodology is sound, reads as noticeably less polished to a reviewer trained in either tradition, and is genuinely worth a dedicated, line-by-line consistency check during your final manuscript review before submission.
