Prevalence and Characteristics of Alcohol Use in Substance-Involved Deaths in St. Louis, Missouri, From 2011 to 2022.
Article in Journal of studies on alcohol and drugs, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveAlcohol contributes to a large number of deaths annually, in terms of both deaths fully attributed to alcohol (e.g., alcohol poisoning) and deaths where alcohol is a contributing cause (e.g., motor vehicle accidents). Nationally, alcohol-involved deaths are increasing. This study examines alcohol's role in substance-involved deaths and factors that are associated with alcohol involvement in the St. Louis, Missouri region.
methodThe present study examined 7,641 substance-involved deaths that occurred in the St. Louis, Missouri region. Data were provided by city and county medical examiner offices and comprised all substance-involved deaths between 2011 and 2022. We examined the prevalence of alcohol stratified by manner of death, sex, and race. We conducted logistic regression predicting odds of alcohol involvement based on demographic factors, presence of medical conditions, involvement of other substances, and year of death.
resultsOverall, 26.29% (2,009/7,671) of substance-involved deaths involved alcohol, and annual alcohol-involved deaths increased by 54.33% from 2011 to 2022. Most substance-involved deaths were overdose deaths (82.54%; 6,307/7,641). Alcohol-involved overdose deaths increased by 60.76% from 2011 to 2022. Prevalence of alcohol was higher for overdose deaths involving opioids and benzodiazepines (18%-24%) than for other drug classes (7%-16%). Odds of alcohol involvement in overdose deaths increased with age (odds ratio = 1.02, 95% CI [1.01, 1.02]) and were higher for males (odds ratio = 1.67, 95% CI [1.43, 1.96]).
conclusionsThe St. Louis metropolitan area saw increases in alcohol-involved fatalities for all manner of deaths, particularly overdose deaths and deaths among Black men. To improve prevention strategies for alcohol fatalities, further research is needed to investigate the role of alcohol in polysubstance overdose deaths.
