Investigating Disparities in Prescription Drug Use Among Mexican Americans and Non-Hispanic Whites.
Article in Journal of racial and ethnic health disparities, 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
backgroundMexican Americans are less likely than non-Hispanic Whites to report prescription drug use. This study explores mediating factors, disparities within chronic conditions, and variations in prescription drug use by nativity.
methodsWe analyzed data from the National Health and Nutrition Examination Survey (2005-2016). Using survey-adjusted logistic regression models adjusted for age and gender, we estimated odds ratios (OR) for the association between ethnicity and prescription drug use in the past 30 days. Mediation analyses identified factors explaining this association. We also examined medication use for chronic conditions (diabetes, hypertension, hyperlipidemia, and depression) and variations in use by nativity.
resultsMexican Americans had lower odds of using prescription drugs (adjusted OR (aOR) 0.38; 95% CI 0.34-0.42). In mediation analyses, lack of prescription drug coverage (proportion mediated (PM) 34.4%; 95% CI 25.1-46.7) and ≤2 health visits per year (PM 19.9%; 95% CI 13.6-28.1). explained a significant portion of the disparity. Contrastingly, poor health status narrowed the gap (PM -13.8%; 95% CI -16.3- -11.1). Mexican Americans with hypertension (AOR 0.79; 95% CI 0.64-0.96) and depression (AOR 0.50; 95% CI 0.33-0.75) had lower odds of receiving medication. Immigrant Mexican Americans had lower odds of using prescription drugs (aOR 0.25; 95% CI 0.22-0.29) compared to U.S.-born individuals (aOR 0.62; 95% CI 0.54-0.73).
conclusionThis study highlights an unmet treatment need for those with chronic conditions in the Mexican American community, with particularly notable disparities among immigrant Mexican Americans. Addressing these issues is crucial for improving healthcare equity.
