How do I document a GRADE downgrade for indirectness across populations?

Document a GRADE indirectness downgrade by naming the specific population difference, tying it to the included studies, and recording the number of levels downgraded in an evidence-profile footnote that another reviewer can audit.

GRADE rates certainty of evidence with explicit criteria and outcome-level judgements, so the indirectness decision belongs at the outcome level and should state which element of the question differs from the available evidence. Cochrane guidance treats indirectness as part of applicability and certainty, which means the footnote should connect the judgement to the review question and the studies that answer it.

Steps to build the footnote

1. State the review question element that differs. Write the target population next to the population actually studied, and name the specific difference (for example, a narrower age band or a different care setting). Expected result: a reader can see exactly which mismatch triggered the judgement.
2. List the studies that carry the mismatch. Cite the included studies whose participants create the indirectness, so the downgrade is traceable to evidence rather than to a general impression. Expected result: each cited study maps to the stated difference.
3. Record the number of levels downgraded. Write whether certainty moved down one or two levels for indirectness and keep that number consistent with the outcome-level rating. Expected result: the footnote and the Summary of Findings rating agree.
4. Note the scope of the effect on certainty. Explain whether the mismatch affects the whole body of evidence for that outcome or only part of it, so a reviewer can see the reach of the downgrade. Expected result: the footnote distinguishes a partial from a full downgrade.
5. Close with the resulting certainty rating for that outcome. State the final level after the indirectness downgrade and any other domains applied. Expected result: the footnote ends with an auditable rating a second reviewer can check against the included studies.

Keep the footnote short and factual. Name the population difference, the studies involved, and the levels downgraded; that trio gives another reviewer the trail needed to reproduce the judgement.
