Effects of a Sugar-Sweetened Beverages Tax on Caries in Italy: A Modelling Study.
Article in Caries research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
<p>Introduction: Despite efforts to reduce sugar consumption, Italy continues to experience high levels of caries, particularly among 12-year-old children. The introduction of a sugar tax is one strategy that gained traction as a mean of curbing excessive sugar intake. This study aimed to assess the potential impact of a sugar tax on reducing caries prevalence through the analysis of two scenarios: a hypothetical implementation of the tax in 2008 (Scen
methodsThe evaluation utilizes a Markov model to evaluate the health and economic outcomes of a 20% ad valorem tax on sugar-sweetened beverages. Outcomes included the caries experience, as DMFT index and QALYs (Quality-Adjusted Life Year/s), direct dental costs, and indirect costs as forgone earnings due to care, assuming a 100% pass-through to consumers. A 3% annual discount rate was applied to all costs. Sub-analysis also included geographical macro-areas of Italy (North-West, North-East, Centre, South, Islands), based on main socioeconomic determinants. A probabilistic sensitivity analysis, involving a Monte Carlo simulation with 1,000 iterations, was conducted to assess the robustness of the model, generating estimates of mean values and 95% uncertainty intervals.

conclusionIntegrating a sugar tax into a broader public health strategy can significantly reduce caries and healthcare costs, especially in disadvantaged settings. These findings highlight the need for policymakers to pair sugar taxes with additional preventive measures for optimal public health outcomes. </p>.
