Trial report in Journal of medical Internet research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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
backgroundThe expansion of e-mental health services offers diverse treatment options. As the variety of available interventions grows, helping individuals navigate these options effectively becomes essential.
objectiveThis study evaluates the effects of a decision aid for users when choosing between guided internet-based psychological interventions and in-person psychotherapy.
methodsA web-based, randomized controlled trial was conducted with 148 Chinese-speaking adult participants from Hong Kong with Patient Health Questionnaire-9 (PHQ-9) scores ≥10 (indicating clinical depression). Participants were recruited by electronic direct mail, social media, university mass mail, and online advertising then randomly assigned to either the decision aid intervention group or the attention control group. The study's assessments were conducted online through self-administered questionnaires before and after the intervention, while the intervention was delivered via Zoom. The decision aid group underwent a brief interactive, self-directed, web-based decision aid. The decision aid included psychoeducation on depression and treatments, a comparison between internet-based interventions and face-to-face therapy, and personalized reports for value clarification. The attention control involved an unguided web search on mental health information. Primary outcome measures included decision conflict (measured using the SURE tool and Decision Conflict Scale), while secondary outcomes included stage of decision-making, satisfaction with decision, perceived benefits and risks, and likelihood of service utilization.
resultsTime-by-intervention interactions in ANOVA were found, which indicated that the reduction in decisional conflict was more significant in the decision aid group than in the control group, as measured using the brief SURE tool (F
conclusionsThis study demonstrates the extent of the utility and value of a decision aid for assisting individuals with depressive symptoms make informed choices related to e-mental health. Decision aids may facilitate the uptake of digital mental health services. Future research should explore the behavioral and long-term impact and generalizability of decision aids in applied settings.
