Information source and search strategy
X.Z. performed the search in 5 databases (PubMed, EMBASE, PsycINFO, Web of Science, and Scopus) from inception to 13th March 2023. We used Medical Subject Headings (MeSH) and text words for the concepts: 1) early-term delivery, 2) LGA, and 3) cognitive and/or academic outcomes. No date and language restrictions were applied. If the published language was not English, we used an AI translator (DeepL. SE, Germany) to perform the translation. Full search strategies are shown in Appendix S1.22 In addition, X.Z. performed a hand search based on relevant systematic reviews on 21st September 2023. All references were imported in EndNote 20 (Clarivate, London, United Kingdom).
