GRADE Evidence Profiles

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 decision-relevant thresholds and the range of effects compatible with the interval. Do not apply unsupported universal event-count rules.

Publication Bias

Consider missing studies/results, selective reporting, small-study effects, sponsorship patterns, registrations, protocols, and reporting availability.

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.

Helper

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