Geospatial analysis of area-level social and behavioral factors associated with short interpregnancy intervals in North Carolina, U.S.
Article in Preventive medicine reports, 2025. 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: Short interpregnancy intervals (sIPI), defined as six months or less, are associated with adverse birth outcomes and are influenced by socioeconomic factors, which reflect a complex interplay between health outcomes, social factors, health behaviors, and geographic contexts. This study aims to examine the spatial distribution of sIPI across North Carolina, in the Southeast United States (U.S.), and assess its association with social and behavioral factors. Methods: We used secondary data from the North Carolina State Center for Health Statistics and the U.S. Census Bureau spanning 2018-2022 to analyze the spatial distribution of sIPI. Associations between sIPI and social and behavioral factors-including race, fertility age, educational attainment, poverty rates, transportation, prenatal smoking, prenatal care in the first trimester, and breastfeeding initiation rates-were assessed using ordinary least squares and spatial lag models. Results: County-level analyses revealed significant spatial autocorrelation of sIPI in North Carolina. Mecklenburg County had the highest number of cases ( Conclusions: Findings emphasize the need for targeted public health interventions such as comprehensive school-based sexual health education and group-level prenatal care programs to reduce the prevalence of sIPI, prevent subsequent adverse birth outcomes, and mitigate geographic health disparities in North Carolina, U.S.
