Assessment of Emerging Technologies to Support Individuals With At-Risk Alcohol Consumption: Pilot Controlled Investigation Study.
Article in JMIR formative research, 2026. 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
Background: The Swedish National Board of Health and Welfare recently updated the national guidelines for at-risk consumption of alcohol. Nearly 30% of the Swedish population now falls under the at-risk category and should be provided with support. Objective: This project aims to identify and evaluate efficient, scalable tools to support individuals with risk-prone alcohol consumption. The project seeks to explore innovative, accessible technologies that could be implemented in large-scale public health interventions. Methods: A pilot-scale clinical study was conducted to assess the feasibility of using emerging technologies for this purpose. Eight healthy volunteers participated in controlled alcohol consumption while being monitored through 2 methods: an eye-scanning tool integrated into a standard mobile phone and saliva sampling for biomarkers such as serotonin and orexin. Results: Eye-scanning parameters began to shift in some participants at approximately 0.4 to 0.5 per mille blood alcohol concentration, particularly in the form of impaired eye convergence. Furthermore, at around 0.5 per mille, participants encountered practical difficulties in managing the eye-scanning app. Salivary biomarkers did not show any clear correlation with alcohol intake, presumably due to the low number of participants. Beyond biological findings, the study also generated important procedural insights for designing a large-scale clinical study. Conclusions: Eye scanning showed potential as a noninvasive and accessible method for detecting and monitoring moderate alcohol consumption effects, while serotonin and orexin biomarkers were not informative in this context. On the basis of these findings and procedural learnings, eye-scanning tools warrant further investigation in larger clinical studies aimed at developing scalable support for risk-prone alcohol consumption.
