Social determinants of health affect disease severity among preschool children with sickle cell disease.
Article in Blood advances, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
abstractIndividuals with sickle cell disease (SCD) face the burden of managing a lifelong chronic illness, increasing vulnerability to social determinants of health (SDoH). However, how SDoH contributes to health disparities is understudied. We hypothesized that preschool children with SCD living in poor neighborhoods with higher socio-economic distress would experience increased acute care utilization (ACU; described as emergency department visits plus hospitalizations) despite disease-modifying therapy. Participants' home addresses (aged 0-6 years) were mapped using census tract environmental data from the US Department of Agriculture Food Access Research Atlas. In multivariable analyses controlled for sickle genotype and disease-modifying therapies (hydroxyurea and chronic transfusion), SDoH indicators, that is, limited access to food, lack of vehicle, low income, and inadequate education, were associated with higher ACU. Living in households with children >1 mile from a supermarket was associated with more hospitalizations (odds ratio [OR], 1.44; 95% confidence interval [CI], 1.13-1.85) and ACU (OR, 1.37; 95% CI, 1.06-1.80) among children with SCD (aged <6 years). In households with at least 1 bachelor's degree, children with SCD experienced less ACU (OR, 0.67; 95% CI, 0.50-0.93) and hospitalizations (OR, 0.67; 95% CI, 0.49-0.92). Preschool children with SCD with limited access to food and transportation are at a higher risk of acute complications despite receiving free evidence-based therapy and social support. The family education level may have a protective effect. Although SDoH in crowded households and health care maintenance visits were not a focus of this study, future research should consider these factors. Understanding the SCD and SDoH association is crucial for directing resources to improve affected children's health.
