A Randomized Controlled Trial of Group-Based Acceptance and Commitment Therapy for Major Depressive Disorder.

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
objectiveMajor depressive disorder (MDD) is a prevalent and debilitating psychiatric condition. This study developed a group-based acceptance and commitment therapy (GACT) program for MDD and conducted a randomized controlled trial to evaluate its effectiveness. The study aims to assess the effects of GACT and identify factors influencing depression recovery in patients with MDD in Korea.
methodsIndividuals diagnosed with MDD, aged 18-40 years, were recruited. Fifty-nine participants were randomly assigned to either the GACT or waitlist control (WLC) group, with 50 participants (27 in GACT and 23 in WLC) successfully completing the program.
resultsThe GACT group demonstrated significant improvements in depression symptoms (Center for Epidemiological Studies-Depression Scale, CES-D), rumination (Ruminative Response Scale-Revised, RRS-R), experiential avoidance (Acceptance and Action Questionnaire-II, AAQ-II), and cognitive fusion (Cognitive Fusion Questionnaire, CFQ) compared to the WLC group (all ps<0.05). Correlation and multivariate regression analyses indicated that improvements in CES-D scores were associated with changes in AAQ-II scores.
conclusionOur findings suggest that the 8-week GACT program has positive effects on depressive symptoms and ACT-related psychological processes in patients with MDD. This study highlights GACT as a promising group-based intervention for depression, potentially reducing the burden of individual psychological treatments.
