Do socioeconomic resources reshape maternal health behaviors? Evidence from a nationally representative network analysis.
Article in Preventive medicine reports, 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
Objective: Maternal health behaviors may co-occur as interconnected patterns. This study, guided by the Family Health Development framework, examined these behaviors as an interconnected system and investigated whether network structure varied by socioeconomic status. Methods: We conducted a cross-sectional secondary analysis of nationally representative data from Korea (Korea National Health and Nutrition Examination Survey [KNHANES], 2022-2023). Seven binary health behaviors were modeled using pairwise φ-correlation networks, and permutation-based Network Comparison Tests compared income and education strata. Results: Fruit and vegetable intake and non-smoking were central to the network, showing multiple connections with other health behaviors. Network structure and global connectivity did not significantly differ by household income or maternal education. Conclusions: Maternal health behaviors operate as an integrated system rather than independent choices in Korea. Targeting central behaviors (dietary behavior and smoking cessation) may yield spillover benefits across multiple health behaviors.
