This is important given online gambling's increasing ascendance internationally [<span>3</span>] and can also be seen as an extension to research on the harmful structural characteristics of many gambling products [<span>4</span>]. My article arranges existing literature on this topic [<span>1</span>], and further argues that three factors have inhibited this research area: the existence of competing terms such as sludge [<span>5</span>], dark patterns [<span>6</span>] and dark nudges [<span>7</span>]; a preponderance of grey literature; and a lack of access to behavioral data.

Although concerning, this rapid yet uneven spread could, if sufficient high-quality data exist, serve as the closest possible equivalent to a real-world controlled experiment.

I fully agree with these points, and contend that further restrictions on the speed of online gambling, to more closely resemble that of land-based gambling, might also logically follow from them [<span>12</span>].

As a team, we care greatly about scientific discourse and opportunities for methodological improvement. This is why we took such efforts to be transparent in the risk of bias methods used in this article, without which such critiques would not be possible. However, right from the outset we note a logical disconnect in the critique by Egger and McKee [<span>2</span>]. The title of their letter starts with ‘unreliable evidence’, yet the authors appear to focus solely on our risk of bias tool rather than on providing a substantive critique of the actual findings from the reviewed studies or our synthesis of them. Regardless, we welcome the conversation.</p><p>In accordance with best practice, our methods were pre-registered and approved through a Cochrane peer review process before our review began [<span>3</span>]. Of our many methodological choices, Egger and McKee focus exclusively on our risk of bias assessment. They rightly acknowledge that there is no consensus among researchers as to how risk of bias assessment should be conducted for ecological studies of the type we include. We, therefore, considered this carefully and developed a risk of bias assessment tool for evaluating population-level studies, which we pre-registered in detail on Open Science Framework (https://osf.io/svgud).</p><p>While some co-authors of included studies participated in developing the risk of bias assessment tool, we consider this a strength and this was appropriately disclosed at the time.

We acknowledge this as a limitation in our review, but note that even had we used a different tool, our findings would remain largely unchanged. This is because the major impact of our risk of bias assessments is on our judgement of the certainty of the evidence (GRADE rating), which was also downgraded because of inconsistency.

The attention to a broad range of outcomes highlights the social benefits of increased alcohol taxes beyond increased revenue; this could be particularly useful for communicating with policymakers and the public.</p><p>Findings show that for each euro invested, the return was 420 euros – this is astonishing, and clearly a ‘win–win’ in terms of simultaneously reducing harms and increasing revenue. However, the tax increases in Lithuania were significant, with a doubling of excise taxes on beer and wine, for example, which resulted in an almost 7% reduction in alcohol affordability [<span>1</span>]. Importantly, similar increases in excise taxes in other countries or regions, such as US states, would not have the same impact on affordability given that alcohol excise taxes account for a much smaller portion of alcohol prices overall [<span>2, 3</span>].</p><p>Furthermore, while the impacts of increased taxes in Lithuania are clear, with some directly attributable to taxes after the tax revenue increased by 20%, several other drastic alcohol policy changes also occurred. Specifically, from 2008 to 2018, Lithuania experienced: excise tax increases, bans on alcohol advertising and increased penalties for drunk driving in 2008; availability restrictions, such as banned off-premise sales from 10:00 PM to 8:00 AM, in 2009; excise tax increases in 2017; and reduced availability by increasing the legal minimum age to 20 years, reducing off-premise sales hours and a near full alcohol advertising ban in 2018. These are all recommended as ‘best buy’ policies by the World Health Organization [<span>4</span>], and it is possible that having these other policies in place synergistically affected outcomes. While Rehm <i>et al</i>.’s ROI analyses focus on a single year to avoid confounding by these other policy changes, this assumes no policy interaction or cumulative policy effects and ignores the behavioral adaptations that had occurred in an already restricted market. Thus, other countries or localities would likely not experience similar magnitudes of ROI unless other restrictions were made.</p><p>Regardless of the magnitude of the ROIs, increased revenue would obviously still be gained in places that increase alcohol excise taxes. This increased revenue is needed in places like the USA, where current taxes cover a small fraction of the costs to society per drink: the most recent available data show that combined federal and state <i>ad valorem</i> and excise taxes averaged to a total of 8 cents per standard drink for beer and 18 cents per standard drink for spirits in 2015 [<span>5</","PeriodicalId":109,"journal":{"name":"Addiction","volume":"120 10","pages":"2105-2106"},"PeriodicalIF":5.3,"publicationDate":"2025-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/add.70165","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815325","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, no statistically significant gene-treatment interaction was seen with ALDH2 rs671 for either TAC [4.46 (-7.88 to 16.80) g/day, P = 0.478] or HDD [-0.91 (-4.60 to 2.78) days/month, P = 0.630].
