App-based conversational agents for tinnitus distress and mental health: A randomised controlled trial.
Article in Internet interventions, 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
Tinnitus is often accompanied by anxiety, depression, insomnia, and significant psychological distress, highlighting the need for accessible, evidence-based interventions. Internet-delivered cognitive behavioural therapy (iCBT) offers a scalable and standardised approach, and chatbots provide an emerging mode of automated delivery. This randomised controlled trial investigated the effectiveness of two app-based iCBT interventions for adults with persistent tinnitus (N = 105). Participants were randomly allocated to one of three conditions for eight weeks: a tinnitus-specific iCBT chatbot (Tinnibot), a general iCBT chatbot for mood and anxiety (Woebot), or a waiting-list control group. Outcomes were assessed at baseline and post-intervention and included tinnitus-related distress (Tinnitus Functional Index; primary outcome), anxiety (Generalised Anxiety Disorder Scale), depression (Patient Health Questionnaire), insomnia (Insomnia Severity Index), mindfulness (Mindful Attention Awareness Scale), and life satisfaction (Satisfaction with Life Scale). Analyses used mixed analysis of variance with an intention-to-treat approach. Both chatbot groups showed significant improvements in anxiety and depression relative to the control group. Tinnibot also produced significant improvements in insomnia severity. Tinnitus distress decreased in both chatbot groups, but only Tinnibot achieved a clinically meaningful reduction. Changes in mindfulness and life satisfaction were modest and did not differ between groups. These findings indicate that chatbot-delivered iCBT can improve comorbid symptoms associated with tinnitus, and that tinnitus-specific tailoring confers additional, clinically meaningful benefits for tinnitus distress.
