Association between infant mortality and community social vulnerability in the USA: a cross-sectional study.
Article in BMJ public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Introduction: Infant mortality rates in the USA demonstrate significant disparities among marginalised racial and ethnic groups. The Centers for Disease Control and Prevention and Agency for Toxic Substances and Disease Registry Social Vulnerability Index (SVI) represents a novel metric to identify patients with increased social vulnerability who may be at risk for worse health outcomes. The objective of this study was to examine the association between county-level SVI and infant mortality rates. Methods: We conducted a retrospective cross-sectional study using the 2018 National Center for Health Statistics Restricted Vitals Statistics birth cohort linked files. We used multivariable negative binomial regression with the county-level count of infant mortality as the dependent variable and SVI as the independent variable and adjusted for maternal factors (proportion of women in each county with each of the following characteristics: aged <19 years, unmarried, inadequate prenatal care, maternal smoking during pregnancy and ≥2 maternal risk factors). Results: There were 3 791 712 infants in the study. Increased social vulnerability, measured by higher county-level SVI score, was associated with increasing infant mortality; quintile 2: adjusted incidence rate ratio (aIRR) 1.07 (95% CI 1.01 to 1.13); quintile 3: 1.11 (1.02 to 1.20); quintile 4: 1.14 (1.03 to 1.28); quintile 5: 1.21 (1.05 to 1.40). Being unmarried (aIRR 1.09 (1.01 to 1.13)), smoking (aIRR 1.05 (1.01 to 1.10)) and having inadequate prenatal care (aIRR 1.09 (1.01 to 1.16)) were also associated with increased infant mortality. Conclusions: County-level infant mortality was associated with increasing levels of social vulnerability in a stepwise fashion.
