Heterogeneity in Racial and Ethnic Disparities in COVID-19 Severity Among Pediatric Inpatients in a National Healthcare Database.
Observational study in Journal of the Pediatric Infectious Diseases Society, 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
backgroundThe COVID-19 pandemic magnified longstanding racial and ethnic disparities in pediatric health, but it is unclear which populations experienced the largest disparities. Our objective was to determine whether disparities in COVID-19 severity differed with respect to patient factors analyzed as effect modifiers.
methodsUsing data from the Premier Healthcare Database, this retrospective cohort study included encounters among inpatients < 19 years old from April 2020 through September 2022 in the USA with a COVID-19 diagnosis. Outcomes of COVID-19 severity were intensive care unit (ICU) admission and ventilator use. Comparisons between Black and White patients and Hispanic and White patients were adjusted for confounders using propensity score weights, reported as risk differences (RDs) in percentage points, and tested for heterogeneity (interaction P) across subgroups of effect modifiers such as complex chronic conditions (CCCs) and insurance status.
resultsOf 8947 pediatric inpatients with primary COVID-19 diagnosis, 3858 were White, 2153 were Black, and 2936 were Hispanic. Among children with a CCC, 14.3% of Black inpatients required a ventilator compared to 9.8% of White inpatients; among children without a CCC, 3.2% of both Black and White inpatients required a ventilator (RDs 4.5 vs 0.0; interaction P = .013). Comparisons of Hispanic and White inpatients showed a similar trend in ventilator use, with larger disparities among inpatients with CCCs and no difference among those without CCCs (RDs 2.7 vs -0.7; interaction P=.031). Among children with government insurance, 25.9% of Black inpatients were admitted to the ICU compared to 20.8% of White inpatients; among children with private insurance, Black and White inpatients had comparable ICU admission rates of 20.0% and 21.4%, respectively (RDs 5.1 vs -1.4; interaction P = .025).
conclusionsAmong hospitalized children, racial and ethnic disparities in COVID-19 severity were largest for those with CCCs or government insurance. These results can help identify target populations for interventions to reduce inequity.
