Effects of Multilevel and Multidomain Interventions on Glycemic Control Among Black Persons with Type 2 Diabetes in the U.S.: A Systematic Review and Meta-Analysis.
Review 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
backgroundType 2 diabetes (T2D) disproportionately affects Black individuals in the U.S., who have higher rates of complications and worse glycemic control. This systematic review and meta-analysis evaluated the effectiveness of non-pharmacological interventions on hemoglobin A1c (HbA1c) in this population.
methodsWe searched PubMed, Scopus, PsycInfo, and CINAHL for randomized controlled trials (RCTs) (1985-2019) enrolling ≥ 50% Black/African American adults with T2D or reporting race-specific HbA1c outcomes, with ≥ 3 months' follow-up. Interventions were classified by levels and domains of influence using the National Institute on Minority Health and Health Disparities framework. Risk of bias and evidence certainty were assessed using Cochrane and GRADE. A random-effects meta-analysis estimated the weighted mean difference (WMD) in HbA1c.
resultsForty-six RCTs (7,864 participants) met criteria. Interventions significantly reduced HbA1c (WMD - 0.38%; 95% CI - 0.51 to - 0.25; I²=50%, τ²=0.08). Multi-domain interventions achieved the largest reductions (- 0.43%; 95% CI - 0.60 to - 0.25; I²=53%, τ²=0.08). Risk of bias was low, and strength of evidence was high. No interventions addressed community/societal levels or the physical/built environment. DISCUSSION: Interventions significantly improved glycemic control among Black adults with T2D. These findings underscore the importance of comprehensive, culturally tailored approaches to diabetes self-management support. Further research is needed on structural interventions to address disparities.
