Illustrating the Role of Infant Well-Child Visits in the Association Between Transportation Insecurity and Acute Health Care Use.
Article in Academic pediatrics, 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
objectiveTo evaluate the role of well-child visits (WCVs) in mediating associations between transportation insecurity and acute health care usage among infants.
methodsThis was a retrospective cohort study of 4114 infants seen for newborn visits at 3 primary care centers between February 1, 2019 and March 31, 2021. Each infant was followed through 15 months of age. The outcome of interest was acute health care usage, defined by high-acuity emergency department (ED) visits or hospitalization. The exposure was transportation insecurity as reported by parents through standardized questionnaires administered during WCVs. We stratified analyses by WCV attendance (≥6 WCVs vs <6 WCVs in the first 15 months of life) to assess whether WCVs mediated associations between acute health care usage and transportation insecurity.
resultsOf 4114 eligible infants, 8.7% endorsed transportation insecurity. Patients reporting transportation insecurity, compared to those who did not, had higher rates of incomplete WCV attendance (60.3% vs 44.2%, P < 0.001), ED visitation (38.0% vs 28.7%; P < 0.001), and hospitalization (19.8% vs 14.1%; P = 0.004). Transportation insecurity, compared to no transportation security, was significantly associated with having <6 WCVs (adjusted odds ratio [aOR] 1.64, 95% confidence interval [CI] 1.29, 2.09), ED visitation (aOR 1.45, 95% CI 1.14, 1.85), and hospitalization (aOR 1.52, 95% CI 1.13, 2.04). However, WCV attendance did not mediate associations between transportation insecurity and ED visits or hospitalizations.
conclusionsTransportation insecurity was associated with fewer WCVs; however, WCV attendance did not mediate associations between acute health care usage and transportation insecurity. Future research could focus on mechanisms linking transportation insecurity to suboptimal health outcomes.
