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
backgroundRaising retail prices on alcoholic beverages preferred by high-risk groups (males, those of low socioeconomic status, and those with heavy alcohol use) might selectively reduce their alcohol consumption. However, the differential impact of beverage-specific price increases on US population groups has yet to be studied. This study aimed to simulate the effect of beverage-specific price increases on alcohol use within subgroups of the adult US population defined by sex, educational attainment, and alcohol use category.
methodsAn individual-level microsimulation of the US population (aged 18-79 years) was used to simulate alcohol consumption from 2000 to 2019 based on individual characteristics (ie, sex, age, race, ethnicity, and educational attainment as a proxy for socioeconomic status categorised as high school degree or less, some college, and college degree or more) and previous alcohol use. The microsimulation model was generated via integration of diverse data sources including decennial US Census data, annual data from the American Community Survey, annual data from the National Vital Statistics System, annual data from the Behavioral Risk Factor Surveillance System, and biennial, longitudinal data from the Panel Study of Income Dynamics. Policy parameters were informed by the existing literature. Four national policy scenarios were compared with a reference scenario without price change in 2019: a uniform price increase of 10% (scenario 1), a uniform price increase of 30% (scenario 2), a beverage-specific price increase of 30% for beer and spirits and 10% for wine (scenario 3), and a beverage-specific price increase of 50% for beer and spirits and 10% for wine (scenario 4). Individual-level effects on alcohol consumption were simulated using beverage-specific own-price elasticities. Sensitivity analysis assessed assumption-based correlation coefficient between alcohol consumption and the individual-level percent reduction in alcohol consumed; and the application of the beverage-non-specific own-price participation elasticity.
findingsScenario 4 had the strongest effect on alcohol use overall and most effectively reduced consumption in high-risk groups: males and females with high alcohol use (more than 60 g of pure alcohol per day for males and 40 g of pure alcohol per day for females) and low educational attainment (high school degree or less) reduced their alcohol use by -17·30% (-17·62 g per day, credible interval [CI] -21·77 to -13·20) and -17·49% (-12·25 g per day, CI -14·72 to -9·58), respectively. In comparison, smaller relative changes were observed among groups at less risk of harm.
interpretationDisproportionate increases in retail prices for the cheapest beverages, beer and spirits, might lead to a greater decline in consumption among high-risk groups. Pricing policies could thus be used as a powerful public health tool to mitigate the unequal alcohol-attributable burden of disease.
