Internet-based versus synchronous cognitive behavioral therapy for gambling disorder: Study protocol for a non-inferiority randomized controlled trial.
Article in Addictive behaviors reports, 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
Background: Despite the availability of effective treatments for Gambling Disorder (GD), help-seeking remains low, and attrition rates are high. Internet-based cognitive behavioral therapy (iCBT) may address barriers to treatment access, but evidence comparing asynchronous iCBT with synchronous CBT (sCBT) is limited. Objective: This study protocol outlines a non-inferiority randomized controlled trial (RCT) comparing the effectiveness of "SpilleFri" (SF), an asynchronous therapist-guided iCBT program, with individual sCBT delivered in-person or via video for adults with GD. Methods: A total of 150 patients diagnosed with GD will be randomized to SF or sCBT. The primary outcome is change in GD severity, measured by the National Opinion Research Center DSM Screen for Gambling Problems (NODS), from baseline to three months post-treatment. Secondary outcomes include gambling behavior, psychological distress, relationship quality, and treatment process variables. Data will be collected at eight time points, including a 12-month follow-up. Non-inferiority will be tested using mixed linear models with a predefined margin of -2 NODS points. Process variables and moderators of treatment response will be explored. Discussion: This trial addresses a critical gap in GD treatment research by directly comparing asynchronous and synchronous CBT formats. If SF proves non-inferior to sCBT, it could offer a scalable, flexible, and resource-efficient alternative for GD treatment. Findings may inform stepped-care models and broaden access to evidence-based interventions.
