Autism Prevalence, Co-occurring Intellectual Disability, and Support Needs Differ for Somali and Hmong Communities in Minnesota.
Article in Journal of autism and developmental disorders, 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
purposePrevious research has documented disparities in autism prevalence and the co-occurrence of intellectual disability (ID) with autism for children from immigrant communities. The current study compared autism prevalence and co-occurrence of ID in 8-year-olds across racial/ethnic groups using data from the Minnesota site of the CDC Autism and Developmental Disabilities Monitoring Network, with a focus on two large racial/ethnic groups: Somali and Hmong.
methodsSystematic review of health and educational records was performed within a defined geographic area, and data were combined from 2014 to 2016 surveillance years to obtain adequate sample sizes to compare prevalence and co-occurrence of ID across race/ethnicity.
resultsSomali children had a higher autism prevalence compared to Hispanic, Hmong, and non-Hmong Asian children, with prevalence ratios (PR) of 1.8, 2.1, and 2.1, respectively. Hmong children had a significantly lower autism prevalence compared to White (PR 0.6) and non-Somali Black (PR 0.7) children. Significant differences in co-occurring ID status were found by race/ethnicity.
conclusionIdentifying subgroups of children with higher prevalence of autism or greater co-occurring ID can inform public health policy and improve outcomes for individuals with autism and their families. Differences in prevalence and co-occurring ID by race/ethnicity may suggest barriers to service utilization.
