Figure 2 Literature Search and Study Selection Flowchart
Retired figure asset (withdrawn)
This historical figure was WITHDRAWN. It is not part of the current evidence overview (2026.10-rc2 and all later revisions, including the November 2026 accuracy review). Its content has been replaced with this notice because its counts or comparative estimates were never substantiated. The filename is kept only so that old links resolve; the title in the filename does not mean a search flowchart, efficacy percentages or any other figure content exists in the current work.
See HISTORICAL_VERSION_NOTICE.md for a description of the withdrawn figures, and MANUSCRIPT.md and EVIDENCE_AUDIT.md for the current record.
