| Summary: | Aim: To evaluate how transportability methods are currently used for real-world evidence (RWE)
generation to inform good practices and support adoption and acceptance of these methods in the
RWE context. Methods: We conducted a targeted literature review to identify studies that transported
an effect estimate of the clinical effectiveness or safety of a biomedical exposure to a target real-world
population. Records were identified from PubMed-indexed articles published any time before 25 July
2023 (inclusive). Two reviewers screened abstracts/titles and reviewed the full text of candidate studies to
identify the final set of articles. Data on the therapeutic area, exposure(s), outcome(s), original and target
populations and details of the transportability analysis (e.g., analytic method used, estimate transported,
stated assumptions) were abstracted from each article. Results: Of 458 unique records identified, six were
retained in the final review. Articles were published during 2021–2023, focused on the US/Canada context,
and covered a range of therapeutic areas. Four studies transported an RCT effect estimate, while two
transported effect estimates derived from real-world data. Almost all articles used weighting methods
to transport estimates. Two studies discussed all transportability assumptions, and one evaluated the
likelihood of meeting all assumptions and the impact of potential violations. Conclusion: The use of
transportability methods for RWE generation is an emerging and promising area of research to address
evidence gaps in settings with limited data and infrastructure. More transparent and rigorous reporting
of methods, assumptions and limitations may increase the use and acceptability of transportability for
producing robust evidence on treatment effectiveness and safety. |
