SARS-CoV-2 Prevalence in a Delivering Refugee Population: Refugee Status, Payor Type, Race, and Vaccination Status.
Article in Journal of immigrant and minority health, 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
Underserved communities were disproportionately affected during the coronavirus (COVID-19) pandemic. Limited data exist on the impact of COVID-19 among refugee populations because refugee status is not often classified in electronic medical record (EMR) systems, unlike race or primary language. The study aim was to evaluate the PCR-based prevalence of SARS-CoV-2 in a delivering population over the first 2 years of the pandemic by refugee status, ethnicity, insurance, and vaccination status. A cross-sectional study examined parturient patients admitted to an urban safety-net hospital from May 2020 to May 2022 who were tested for SARS-CoV-2on admission. Percentages and prevalence ratios of SARS-CoV-2 between refugee status, insurance type, vaccination status, and race/ethnicity were calculated across four time periods, corresponding with variant surges of the pandemic. 3,502 patients delivered, 476 (13.6%) were refugees. Self-pay (46.4%) and Medicaid (46.4%) were the most frequent insurance types with a Hispanic predominance (64.5%) by race/ethnicity. Only 12.8% of patients received at least one vaccine before delivery: 13.2% in non-refugees versus 10.3% refugees 192 (5.5%) of the mothers tested positive during the study period with 6.1% refugees positive versus 5.4% among non-refugees, (prevalence ratio, 1.13; P = 0.53, 95% confidence interval [0.77, 1.66]). Positive tests ranged between 4.7% and 6.3% across insurance types and between 4.4% and 7.5% across race/ethnicity categories. The highest prevalence ratio (refugee/non-refugee) of 2.01 was during the Delta Surge (P = 0.12, 95% confidence interval [0.84, 4.82]) and the lowest prevalence ratio of 0.64 was during the Omicron Surge (P = 0.21, 95% CI [0.32, 1.30]). Among refugees when examined by primary language, 51.7% of positive tests were from those speaking languages of the African Great Lakes region (Kinyarwanda, Kirundi, Swahili, Kiswahili). We observed only small differences in SARS-CoV-2 prevalence between refugees and non-refugees or in vaccination status. Variations in prevalence ratio were seen by refugee status by variant surge. Subsets of the refugee population, when grouped by language/region, appeared to be more affected. This warrants future research on the impact of the SARS-CoV-2 pandemic on specific refugee communities, rather than refugee communities as a heterogenous unit.
