The tracking and reducing alcohol consumption (TRAC) intervention for veterans living with HIV/AIDS: results from a pilot randomized waitlist-controlled trial.
Trial report in Addiction science & clinical practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03746600 (A Telemedicine and mHealth Intervention for Reducing Alcohol Consumption Among People Living With HIV/AIDS), which is not on this 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.

Abstract
backgroundVeterans with HIV/AIDS (VWH) frequently report alcohol misuse, which can impact antiretroviral therapy (ART) adherence and lead to poorer clinical outcomes. The TRAC (Tracking and Reducing Alcohol Consumption) intervention was developed to help VWH reduce alcohol use and its associated consequences. TRAC is delivered via mobile device, incorporates eight counseling sessions based in cognitive behavioral therapy and motivational interviewing, and utilizes mobile surveys and breathalyzers for daily monitoring of alcohol and ART use.
methodsWe conducted a pilot randomized waitlist-controlled trial (N = 50). Participants were allocated to an immediate intervention group (N = 26), which received the TRAC intervention and completed twice-daily monitoring of alcohol and ART use for 8 weeks, or to a waitlist-control (n = 24), which started TRAC after 8 weeks. Participants provided ratings of intervention sessions and completed questionnaires assessing alcohol use, ART adherence, and treatment self-efficacy at baseline, 8, 16, and 24 weeks. Analyses included correlations and descriptive statistics for examining feasibility and acceptability, difference-in-differences analyses to compare changes between groups at the 8-week timepoint, matched pair tests to assess changes in alcohol use during the intervention, and general linear models to investigate long-term effects on outcomes with a pooled sample.
resultsResults indicated high feasibility and acceptability: 84% of participants were retained through the intervention and all follow-ups, average intervention session ratings were 9.6 (out of 10), and participants completed a median of 85% and 78% of mobile surveys and breathalyzer readings, respectively. While not statistically significant due to low power, there was a trend of decreased binge drinking episodes and fewer missed HIV medication doses in the intervention group compared to control. When pooling data among participants from both groups to examine long-term effects, TRAC was associated with reductions in several drinking-related outcomes.
conclusionsHigh acceptability and feasibility, as well as preliminary evidence that the intervention may reduce alcohol use relative to control, suggest that the TRAC intervention is promising for VWH and warrants further evaluation in a randomized controlled trial with adequate power to detect effects. If shown to be efficacious, TRAC has potential to be a highly scalable and acceptable intervention for delivery among VWH.
