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
objectiveThis study aimed to investigate the effects of white noise therapy combined with cognitive behavioural therapy (CBT) on clinical manifestations, psychological stress and sleep quality in patients with depression.
methodsThis study retrospectively analysed 136 patients with mild to moderate depression treated between January 2022 and December 2024. On the basis of their treatment timeline, the patients were divided into conventional group (n = 47, conventional therapy, January-December 2022), CBT group (n = 45, conventional therapy + personalised CBT, January-December 2023) and white noise group (n = 44, conventional therapy + personalised CBT + white noise therapy, January-December 2024). The clinical symptoms [24-item Hamilton Depression Scale (HAMD-24), Stroop test], psychological stress [Perceived Stress Scale (PSS-10), Gross Emotion Regulation Questionnaire (ERQ)], sleep quality [Pittsburgh Sleep Quality Index (PSQI)], cognitive fusion level [Cognitive Fusion Questionnaire (CFQ-F)], hope level [Herth Hope Index (HHI)] and experiential avoidance degree [Acceptance and Action Questionnaire-II (AAQ-II)] were compared before and 12 weeks post-treatment.
resultsCompared with pre-therapy levels, statistically significant improvements at 12 weeks were observed for all three groups (P < 0.05). These included reductions in HAMD-24 scores, Stroop mean reaction time, PSS-10 scores, ERQ suppression subscale scores, PSQI scores and AAQ-II scores, along with increases in Stroop correct responses, ERQ reappraisal subscale scores, CFQ-F scores and HHI scores. Post-therapy between-group comparisons revealed that the white noise group exhibited superior outcomes versus both the conventional and CBT groups across all metrics, while the CBT group outperformed the conventional group on all assessment parameters (P < 0.05).
conclusionThe findings of this retrospective study suggest that white noise therapy combined with CBT may have positive effects on patients with mild to moderate depression, including improvements in clinical symptoms, psychological stress response and sleep quality. These benefits were demonstrated through reduced depression severity, increased use of cognitive reappraisal strategies, enhanced cognitive fusion, reduced experiential avoidance and elevated hope levels.
