Resolve a borderline study’s eligibility before using its result

Turn the review boundary into a decision rule

Cochrane Chapter 4, checked 7 November 2026, specifies independent final eligibility judgments and advance disagreement resolution for Cochrane reviews. It also allows unresolved cases to await assessment. The business-review workflow here adapts the decision discipline without claiming that Cochrane requirements govern every editorial project.

Write the review’s eligibility criteria in terms another researcher can apply to a report. Distinguish the target population, activity, comparison, outcome and study design where each matters. Avoid a criterion such as high-quality research when nobody can explain what evidence satisfies it. Separate admission to the review from later assessment of how much weight the evidence deserves.

Test the wording against an obvious eligible case, an obvious ineligible case and a genuinely doubtful case. Use public reports or invented descriptions without collecting new personal information. Ask whether disagreement comes from missing facts or from different interpretations of the rule. Those problems need different remedies: more information will not fix a criterion that means two things.

Keep the original judgments visible

Have the assigned reviewers make their decisions through the agreed process before the adjudication discussion. Record the criterion at issue and the report location supporting each judgment. A final consensus alone cannot explain how the disagreement arose. Preserve the original assessments in the working record so later editors can distinguish a corrected oversight from a substantive rule change.

Keep the report’s attractive or disappointing result out of the admission rationale. If a reviewer says the study is not useful, ask whether that means it fails a stated criterion, lacks information or simply offers an inconvenient finding. Do not invent a new exclusion rule after seeing the answer. A genuine change to the review boundary requires a visible decision about previously assessed cases too.

Resolve the precise disagreement

Compare the relevant passages, not the reviewers’ confidence or seniority. If one person missed a method detail, correct the record and identify the evidence. If the criterion itself is ambiguous, refine its interpretation and determine which other cases require reassessment. If a qualified adjudicator is needed, give them the disputed criterion and both reasons rather than asking for a general opinion of the paper.

When essential information is unavailable, record what fact would resolve the case. Do not translate uncertainty into an exclusion merely to complete a flow diagram. An author query may be appropriate in a real review, but sending one requires the normal authorization and is not performed by this exercise. Keep the case’s unresolved status visible to the person interpreting the evidence base.

Close admission without deciding the finding

Issue an admission record with the applied rule, supporting location and decision. For exclusions, use a specific reason that another reviewer can understand. For unresolved cases, retain the outstanding question and its practical consequence. A reviewer should be able to see whether a potentially important report was absent because it was ineligible, unavailable or still awaiting clarification.

Check the consequences of any clarified rule across the candidate set. Do not repair only the disputed case while leaving earlier judgments inconsistent. Keep this admission decision separate from later extraction, bias assessment and contribution to a particular synthesis. A study can be eligible for the review yet provide limited information for one question. Admitting it is not an endorsement of every conclusion its authors make.

Make the reasoning concrete.

A fictional trade publisher reviews trials of self-service documentation for adult business users. One report concerns trained internal staff, while the stated scope concerns first-time external users. Reviewers disagree about whether the populations are equivalent for this review.

The publisher resolves the population criterion before using the study result. Missing information would remain an open admission question rather than an assumed match.

1. Rule

   Which exact criterion decides this case?

2. Evidence

   What passage supports each interpretation?

3. Disagreement

   Is the problem missing information or ambiguous wording?

4. Disposition

   Is the case included, excluded or unresolved?

5. Consistency

   Which earlier judgments must be revisited after clarification?

Watch for the wrong conclusion.

• Using an attractive result as an admission reason.
• Erasing original judgments after consensus.
• Calling missing information a failed criterion without justification.
