Association of race, ethnicity, and pediatric long COVID and MIS-C: a systematic review and meta-analysis.
Synthesis in BMC infectious diseases, 2026. 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
backgroundPediatric long COVID and other post-COVID conditions, particularly in relation to racial, ethnic, and household social determinants, are not yet well understood. This study aims to synthesize evidence on racial and ethnic disparities in pediatric long COVID and related conditions like MIS-C.
methodsA systematic review and meta-analysis were performed on studies reporting post-COVID conditions and outcomes by race and ethnicity. Studies were identified through comprehensive database searches, screened for relevance, and assessed for quality. Data on race, ethnicity, and social determinants were extracted and analyzed using random-effects models to estimate pooled odds ratios. Sensitivity analyses were performed to address potential publication bias.
resultsNon-Hispanic Black children had significantly higher odds of ICU admission (OR 1.89, 95% CI 1.01-3.28), MIS-C development (OR 2.37, 95% CI 1.43-3.90), and PIMS-TS (OR 16.28, 95% CI 9.24-28.70) compared to Non-Hispanic White children. Although Hispanic children showed a protective effect against severe MIS-C (OR 0.77, 95% CI 0.64-0.93), their MIS-C incidence remained higher (OR 2.70, 95% CI 1.10-6.65). Elevated risks of MIS-C death were observed for Asian/Pacific Islander (OR 6.79, 95% CI 1.2-38.52) and Alaskan Indian/Native American children (OR 4.07, 95% CI 3.4-44.53). Additionally, Asian children had increased odds of PIMS-TS (OR 6.42, 95% CI 2.70-15.27), while groups labeled as 'Other' were at higher odds for both PIMS-TS (OR 9.75, 95% CI 3.04-31.30) and MIS-C (OR 2.36, 95% CI 1.18-4.71).
conclusionsSignificant racial and ethnic disparities in pediatric long COVID, and MIS-C outcomes emphasize the need for targeted interventions addressing social and healthcare inequities. CLINICAL TRIAL NUMBER: Not applicable.
