Evaluating Maternal and Fetal Risk in Preeclampsia Using Thyroid and Inflammatory Markers: A Naive Bayes and Network Analysis Approach.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPreeclampsia is a significant factor in maternal and fetal morbidity globally, highlighting the necessity for early risk assessment and intervention. This study introduces a machine learning (ML) approach that integrates maternal thyroid profiles and C-reactive protein (CRP) levels to predict preeclampsia and potential fetal thyroid abnormalities. MATERIALS AND
methodsA cross-sectional dataset of 174 pregnancies (91 normal, 83 preeclampsia) was analyzed. EN regularization identified maternal CRP, thyroid-stimulating hormone (TSH), and anti-thyroperoxidase antibody as the primary predictors of preeclampsia, with CRP being the most significant contributor.
resultsA Naive Bayes model trained on these markers achieved remarkable predictive performance, with an accuracy of 92.5% ± 7.7%, a sensitivity of 99.9%, and a specificity of 86.1% ± 1.4%. Network analysis identified a substantial maternal-fetal connection via FT3 and cord TSH, establishing the foundation for a secondary NB model predicting fetal hypothyroidism. The model exhibited moderate overall accuracy (63.7% ± 5.3%) but demonstrated significant improvement in the preeclampsia subgroup (73.3% ± 1.7%) while maintaining 100% sensitivity. CRP levels differed significantly between groups, underscoring its role as a systemic inflammatory marker in the pathogenesis of preeclampsia.
conclusionsThis comprehensive ML architecture links maternal indicators to fetal outcomes, demonstrating the practicality of using interpretable, probabilistic models in prenatal care. The results support early risk classification and targeted monitoring for high-risk pregnancies, emphasizing the clinical value of integrating thyroid and inflammatory markers into maternal screening. Future validation across varied cohorts may facilitate the clinical implementation of these models to enhance maternal-fetal health outcomes.
