This problem is addressed in PRISMA 2020 (Q21), ROBIS (P2 D2) and MECIR (C39). Relevant studies may be retrieved by searches but then not selected for inclusion into the review either at screening or full text retrieval stage. The study selection process should ideally be performed in duplicate and against pre-specified eligibility criteria for titles and abstract to ensure that relevant studies are not erroneously excluded.
