The Lancet Public Health has published a correction to a 2026 randomised controlled trial examining the effects of added-sugar warning labels on restaurant menus in the United States. The amendment, made public on 23 June 2026, clarifies visual elements in the study’s primary figure to ensure accurate representation of the labelling icons used during the trial.
Key takeaways
- The Lancet Public Health corrected red icon depictions in figure 1 of a menu-labelling study to match icons used in the actual trial
- The correction maintains the integrity of the original study design and findings while improving visual accuracy
- Menu warning labels remain a focus of public health research as policymakers evaluate strategies to reduce added-sugar consumption

What the Correction Addressed
According to the published correction, the red icons depicted in figure 1 of the original article required amendment to accurately reflect the visual design of warning labels that participants encountered during the randomised controlled trial. This type of correction is routine in peer-reviewed publishing when graphical representations need alignment with actual experimental materials.
The study, led by investigators including Dr. Yan Huang and colleagues, examined how added-sugar warning labels influence consumer choices when displayed on restaurant menus in a digital environment. The correction ensures that readers can now view the exact visual stimuli that trial participants were shown, strengthening transparency in the research record.
The Broader Context of Menu Labelling Research
Menu warning labels represent one evidence-based policy tool examined by public health researchers to address rising rates of added-sugar consumption. The Lancet family of journals regularly publishes rigorous trials testing interventions aimed at improving dietary choices. This particular study’s focus—conducted as an online randomised trial—reflects modern research methods that can rapidly scale behavioural experiments to representative samples.
According to the published record, the research team included Roberto CA from the University of Pennsylvania and Hall MG from Northwestern University Feinberg School of Medicine, among other co-authors. Their investigation aligns with growing international interest in understanding how visual cues on menus influence purchasing behaviour, particularly for products high in added sugars.
The red icons in figure 1 have been amended to accurately correspond to those used during the trial, as of 23 June 2026.

Implications for Dietary Policy and Food Labelling
Corrections to published research strengthen public confidence in the scientific record by demonstrating editorial vigilance and transparency. When figures are amended to match actual experimental materials, it reinforces that the underlying trial design and findings remain robust. For policymakers evaluating menu-labelling interventions, having accurate visual information about how labels were presented is essential for informed implementation decisions.
The research team’s work contributes to the evidence base that informs public health agencies considering regulation of food labelling and consumer information on menus. As documented in health policy initiatives, many jurisdictions are exploring whether front-of-package or point-of-purchase warnings reduce consumption of products with excessive added sugars. This trial’s findings—now with corrected visual fidelity—help guide those policy decisions.
What this means
Frequently asked questions
Why would icons in a published figure need correction?
Corrections of this type occur when graphical elements in a manuscript do not precisely match the actual stimuli used in the study. In randomised trials, ensuring that figures accurately depict what participants experienced is essential for reproducibility and transparent reporting. The Lancet Public Health editorial process caught this discrepancy and published an amendment on 23 June 2026.
Does a figure correction affect the study’s conclusions?
No. A correction to visual representation in a figure does not alter the trial’s underlying methodology, sample size, statistical analysis, or findings. The red icons are now accurately depicted to match what was shown to participants, which enhances clarity but does not change the reported results or their interpretation.
How do added-sugar warning labels affect consumer behaviour?
Research published in peer-reviewed journals, including trials in recent studies, indicates that visual warning labels can influence food choices by increasing salience of nutritional content. The Huang et al. trial examined this effect in a controlled online setting. Real-world impact depends on label design, placement, and consumer demographics, making continued research essential for policy refinement.
The publication of this correction reflects the Lancet Public Health’s commitment to maintaining accuracy and transparency in the scientific record. As menu-labelling policies expand globally, ensuring that trial data are reported with precision will support evidence-based public health decision-making. Readers interested in menu-labelling interventions and dietary policy can access the full corrected article and should note the amendment date when citing this research in future work.
