Long-term efficacy of an optimized online gambling self-exclusion procedure with extended suspension of commercial solicitations: a randomized controlled trial.
Trial report in Harm reduction journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05413564 (Impact of a Self-Exclusion Procedure Optimized by an Extension of the Suspension of Commercial Solicitations), 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
backgroundMost individuals self-excluding from gambling have lost control over their gambling behavior. Commercial solicitations are prohibited during the self-exclusion period, but resume immediately afterwards. The self-exclusion system appears insufficient, particularly for short self-exclusions and among the heaviest gamblers. We assessed the impact of extending suspension of commercial solicitations on gambling intensity.
methodsIn this parallel randomized study, we included 2548 French online gamblers who self-excluded for up to 3 months from May-November 2022. They were assigned 1:1 to optimized self-exclusion with extended commercial solicitations ban for 9 months or standard procedure. The primary outcome was the change in total loss over the past 4 weeks at Month 9. We also assessed total deposit, total stakes, compulsivity, number and duration of gaming sessions and subsequent self-exclusions at 6, 9, 12 and 18 months.
resultsParticipants were randomized to the optimized group (n = 1265) or standard group (n = 1283). The results didn't show a significant difference in the reduction in total losses. The optimized group showed significantly reduced 4-week total deposits versus standard group at 6 months (455.68 euros vs. 319.65 euros, p = 0.017), 9 months (451.92 euros vs. 343.21 euros, p = 0.040), and 12 months (484.27 euros vs. 370.02 euros, p = 0.025). Significance was lost at 18 months (492.61 euros vs. 404.73 euros, p = 0.087).
conclusionsAn extended 9-month ban on direct commercial solicitations after self-exclusion significantly reduces gambling deposits during, and 3 months after, the ban. This supports the effectiveness of improving self-exclusion procedure. Future research should explore longer bans and indirect commercial solicitations.
