Purpose
An evidence profile transparently records a human panel's judgments about a body of evidence for each important outcome. It is not an article-scoring shortcut and does not produce a patient-care recommendation.
Use the current GRADE Book and the GRADE Working Group as the controlling methodology. The GRADE Book is replacing the older handbook with progressively updated content.
Non-Automation Rule
Never:
- infer certainty from keywords, abstracts, p-values, journal name, or study design alone;
- count checklist items to calculate certainty;
- treat one study's risk-of-bias judgment as certainty in a body of evidence;
- equate certainty with recommendation strength;
- assign recommendation strength without an Evidence-to-Decision process and a responsible panel;
- invent source citations or downgrade/upgrade rationales.
The bundled checker verifies structure, allowed labels, human attribution, rationale, and source linkage. It does not alter or endorse a judgment.
Unit of Assessment
Rate certainty separately for every critical or important outcome. Include desirable and undesirable effects. Different outcomes may have different:
- bodies of evidence;
- risk-of-bias concerns;
- directness;
- precision;
- reporting bias;
- certainty.
Do not collapse all outcomes into a single study-level grade.
Required Profile Fields
Question
- Population
- Intervention/exposure/index approach
- Comparator/reference
- Outcomes and time horizons
- Setting and decision context
Sources
For every source include:
- stable source ID;
- full citation;
- URL or DOI;
- publication type;
- version/date;
- access date when content is living.
Effect
For each outcome record:
- measure and direction;
- absolute and relative effects when appropriate;
- confidence or credible interval;
- participants and studies;
- follow-up/horizon;
- missingness;
- whether the estimate is adjusted;
- applicability limits.
Do not convert an effect into a clinical instruction.
Certainty Domains
Every domain entry requires a judgment, rationale, source IDs, and human reviewer role.
Risk of Bias
Use a design-appropriate tool. Describe how limitations could change the estimated effect. Do not use a numeric quality score as a substitute.
Inconsistency
Examine the direction and magnitude of effects, interval overlap, heterogeneity, and plausible explanations. A statistical heterogeneity value alone is not the judgment.
Indirectness
Compare population, intervention/exposure, comparator, outcome, time horizon, setting, and evidence pathway with the framed question.
Imprecision
Use the current GRADE Book imprecision chapter: record the target of certainty, prespecified thresholds, and absolute-effect intervals where appropriate. Its human judgments can include extremely_serious concerns (three levels); the checker accepts that label for imprecision without deriving the final certainty. Do not import universal event counts, invent clinical cut points, or count a shared concern twice across domains.
Dissemination Bias (Publication Bias)
The current GRADE Book uses dissemination bias to cover selective availability of evidence, including unpublished and obscurely published results. Consider missing studies/results, small-study effects, time/language effects, sponsorship, registrations, and protocols. Separate selective results within a study from missing evidence across the body of evidence and document overlap with risk of bias. The JSON key remains publication_bias for compatibility; record the broader assessment in its rationale.
Upgrading Considerations
When the selected GRADE approach permits, a panel may consider large effects, dose-response gradients, or plausible residual confounding. Each requires explicit methodology, rationale, and citations. “Statistically significant” is not an upgrading reason.
Final Certainty
Allowed labels:
- high;
- moderate;
- low;
- very low.
Record:
- the final human judgment;
- who made it and in what role;
- date;
- domain-to-final-rating rationale;
- dissent or unresolved issues;
- source IDs.
The label describes confidence in an estimate for an outcome in a defined context. It is not a recommendation and does not imply safety, effectiveness, or authorization.
Evidence to Decision
Recommendation development is outside the automated helper. A qualified panel using an applicable GRADE Evidence-to-Decision framework must explicitly consider, as relevant:
- priority of the problem;
- desirable and undesirable effects;
- certainty of evidence;
- values and variability;
- resources and cost effectiveness;
- equity;
- acceptability;
- feasibility.
Keep the evidence profile and any later recommendation record separate and traceable.
Quality-Control Checklist
- Search and selection methods are documented.
- Outcome definitions and horizons match the question.
- All important benefits and harms are represented.
- Effect estimates include uncertainty.
- Each domain has a human judgment and rationale.
- Every rationale links to source IDs.
- The final certainty is outcome-specific.
- Conflicts of interest and panel roles are recorded.
- Disagreements and updates are versioned.
- No patient-specific or treatment directive appears.

The distributed template intentionally contains unresolved judgments. A non-zero result is expected until qualified humans complete it.
