Alcohol and Other Substance Screening in Bariatric Surgery Candidates: Utility of Self-Report and Toxicology Tests, Including Ethyl-Glucoronide.
Article in Obesity surgery, 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
Following bariatric surgery (BS) patients have an increased risk of alcohol misuse. PURPOSE: This 1-year cross-sectional study in potential BS candidates had several objectives: (a) assess the prevalence of risky drinking, alcohol use disorder (AUD), and other substance use/disorder; (b) compare the prevalence of these behaviors to that of the general Spanish population; (c) determine the proportion of patients with positive results in toxicology tests; and (d) study the predictive factors of risky drinking.
settingtertiary university hospital. MATERIALS AND
methodsAlcohol and other substance use were evaluated with the AUDIT-C and ASSIST questionnaires. Urine tests analyzed several markers (ethyl-glucoronide [EtG] ≥ 500 ng/ml, amphetamine, benzodiazepine, cannabinoid, cocaine, and opioid). The Mini-International-Neuropsychiatric-Interview (5.0.0) was employed to assess psychiatric diagnoses.
resultsAmong 308 candidates for BS, 196 were accepted to participate (69% women; mean age 46.7 ± 10.9 years; mean body mass index 45.6 ± 5.9). AUDIT-C and ASSIST identified 7% and 5% of risky drinkers, respectively. Men were more frequently risky drinkers compared to women (18% vs. 2%) and compared to the general population (18% vs. 8%). Six percent of individuals had AUD, being men the most affected, and 2% met criteria for other substance disorder. Fifteen percent of the sample presented risky tobacco use. Cannabis was self-reported only by males (3%). EtG ≥ 500 ng/ml was present in 15% of the sample, being a risk factor for risky drinking together with the male sex.
conclusionIdentification of candidates at risk for risky drinking can help to prevent any alcohol misuse after BS. The combination of subjective and objective measures improves the validity of the assessment of substance use.
