1 · What the graph read from it

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.

2 · The registry

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 clinical potential of digital interventions for young adults with depression, low engagement remains a persistent challenge. A conversational therapeutic companion agent (TCA) can foster a digital therapeutic alliance to address this barrier. Objective: This study aimed to develop a Wizard-of-Oz TCA prototype integrating behavioral activation, ecological momentary assessment/intervention (EMA/EMI), and gamification, and to evaluate its proof-of-concept feasibility, acceptability, and preliminary clinical efficacy for young adults with depressive symptoms. Methods: 58 Korean young adults ages 20 to 39 (50.0% female) with subclinical to moderately severe depressive symptoms (Patient Health Questionnaire-9) were recruited. The intervention group (n=29) interacted with the TCA for six weeks, while a frequency-matched passive control group (n=29) continued usual routines. Primary outcomes were feasibility (adherence) and acceptability (satisfaction). Secondary outcomes for efficacy (Beck Depression Inventory-II, Generalized Anxiety Disorder-7, Quality-of-Life Enjoyment and Satisfaction Questionnaire-Short Form) were assessed biweekly. Results: Of 58 participants, 57 completed the study. The intervention proved feasible, acceptable, and usable, achieving 69.5% strict on-time EMA adherence, 66.2% behavioral activation routine completion, a mean daily satisfaction of 3.49/5.0, and a mean System Usability Scale (SUS) score of 74.02, meeting Conclusions: The TCA-based intervention is feasible and acceptable, successfully cultivating a digital therapeutic alliance. While preliminary clinical signals are promising, future fully powered randomized controlled trials are required to definitively establish clinical efficacy.
