Overcoming health misinformation in marginalized groups: a systematic review.
Synthesis in International journal for equity in health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundMarginalized populations experience persistent health disparities that may be exacerbated by exposure to health misinformation. This systematic review aimed to identify interventions designed to address health misinformation in marginalized populations and characterize their effectiveness for changing health beliefs, intentions or behaviors.
methodsMedline, Embase, PsycINFO and Web of Science Core Collection were searched from inception to January 2025, with additional hand-searching of journals and citations. All studies were assessed for eligibility by two reviewers. Quantitative, qualitative, or mixed-method studies were eligible if they aimed to address health misinformation in a marginalized population and reported an outcome relating to health beliefs, intentions or behaviors. Studies that focused only on program design or engagement, and those lacking outcome data, were excluded. The Effective Public Health Practice Project Quality Assessment Tool and the National Institute for Health and Care Excellence Quality Appraisal Checklist were used to assess study quality and risk of bias. Findings were described through narrative synthesis.
resultsThirty-two studies met eligibility criteria; seven were assessed as moderate quality, 25 as weak. Studies were classified based on intervention components: message-focused (n = 17); capacity- or trust-building (n = 6); or both (n = 9). Studies of message-focused interventions provided moderate-to-low quality evidence for use of pre/debunking to change misinformation beliefs and to increase intentions to comply with recommended health behaviors. Sixteen studies included community engagement in design, and 14 were delivered by community members; early community participation in ideation, design or delivery was reported to improve engagement and trust in health information, contributing to intervention efficacy. However, most studies had limitations in randomization, blinding, and outcome measurement.
conclusionEvidence on interventions to overcome health misinformation in marginalized populations remains limited and generally weak. Debunking and prebunking approaches show promise in changing health beliefs and intentions in some marginalized groups. Representatives from marginalized populations should be routinely involved in design, delivery and evaluation of such interventions. REGISTRATION: The protocol and search strategy were registered and published in the PROSPERO International Prospective Register of Systematic Reviews (CRD42024550534).
