A total of 1221 singleton pregnancies (19–23 weeks’ gestation) with high risk of delivering small-for-gestational-age newborns were randomly allocated into 3 groups in a 1:1:1 ratio: a Mediterranean diet intervention, a stress reduction program, or usual care. Participants in the Mediterranean diet group received monthly individual and group educational sessions and free provision of extra-virgin olive oil and walnuts. Those in the stress reduction group underwent an 8-week mindfulness-based stress reduction program adapted for pregnancy. Individuals in the usual care group received pregnancy care per institutional protocols. Fetal cardiac function was assessed using cord blood NT-proBNP (N-terminal probrain natriuretic peptide) and fetal echocardiography.

Additionally, fetuses whose mothers followed the Mediterranean diet exhibited higher right ventricular fractional area change (mean [standard deviation], 30.4% [8.3] vs 28.1% [8.9]; <em>P</em>=.03) and thinner myocardial walls (mean [standard deviation], 2.95 [0.55] vs 3.16 [0.58] mm; <em>P</em>=.006) compared with the usual care group.</div></div><div><h3>CONCLUSION</h3><div>Promotion of a maternal Mediterranean diet intervention during pregnancy seems to be associated with a less overloaded and more efficient fetal heart.

While small for gestational age (SGA) is often used as a proxy for FGR, it does not necessarily indicate pathological growth restriction. Given the increasing interest in machine learning (ML) for predicting FGR/SGA, this study systematically reviews ML applications in this domain, evaluating their methodological rigor and reporting quality, following standardized guidelines.</div></div><div><h3>Data Sources</h3><div>The systematic search was conducted in MEDLINE and Scopus on June 21, 2024, following PRISMA 2020 guidelines.</div></div><div><h3>Study Eligibility Criteria</h3><div>Eligible studies implemented ML models for FGR/SGA prediction using routinely available clinical variables and reported at least one area under the receiver operating characteristic (AUROC) and/or accuracy. Exclusions included preprints, conference abstracts, systematic reviews, animal studies, and models relying exclusively on biomarkers or genomics, as not part of the clinical practice.</div></div><div><h3>Study Appraisal and Synthesis Methods</h3><div>Two independent reviewers screened articles with the help of the Rayyan software. Risk of bias was assessed using the PROBAST checklist. Adherence to the guidelines on the transparent reporting of a multivariable prediction model for individual prognosis or diagnosis+artificial intelligence (TRIPOD+AI) was evaluated across methods, results, and discussion sections using a 4-point Likert scale. Sample size adequacy was assessed for each study, accounting for outcome type, predictors, and outcome prevalence.</div></div><div><h3>Results</h3><div>The search identified 272 studies, with 20 meeting the inclusion criteria. Definitions of FGR/SGA were inconsistent, particularly in technical journals. Adherence to TRIPOD+AI guidelines was variable, as no model reported on fairness or heterogeneity across relevant subgroups, and only 15% reported on calibration. Only 30% of studies met the minimum sample size required for ML models, indicating potential overfitting and limited generalizability.</div></div><div><h3>Conclusion</h3><div>Despite the potential of ML models in predicting FGR/SGA, key limitations persist, including inconsistent outcome definitions, underpowered models, and suboptimal reporting of calibration and clinical applicability.
