Evaluation of sleep quality in patients diagnosed with bipolar disorder and major depression during remission period.

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
backgroundSleep disturbances and residual functional impairment are increasingly recognized as important determinants of outcome in mood disorders, even during remission. Persistent disruptions in sleep may reflect underlying pathophysiological mechanisms and contribute to impaired psychosocial recovery. By comparing remitted bipolar disorder (BD) and major depressive disorder (MDD) patients with healthy controls, the present study sought to clarify the extent of these disturbances and their correlates.
aimTo evaluate differences in sleep quality, psychosocial functioning, and insomnia severity among remitted patients with BD and MDD, in comparison with healthy controls. A secondary aim was to examine the clinical and psychosocial factors influencing sleep quality within these groups.
methodsThe study included 135 participants: 45 remitted BD patients, 45 remitted MDD patients, and 45 healthy controls. Sleep quality was assessed with the Pittsburgh Sleep Quality Index, psychosocial functioning with the global assessment of functioning, and insomnia severity with the Insomnia Severity Index. Sociodemographic and clinical characteristics were also recorded. Comparative analyses were conducted to evaluate differences between groups, and regression models were used to identify predictors of sleep quality.
resultsBoth BD and MDD groups demonstrated significantly poorer sleep quality and higher insomnia severity compared with healthy controls. Poor sleep quality was observed in 75.6% of BD patients and 57.8% of MDD patients. Group differences were most pronounced in Pittsburgh Sleep Quality Index subdomains including sleep latency, sleep duration, and habitual sleep efficiency. Regression analysis identified insomnia severity (
conclusionThe findings underscore that even during remission, BD and MDD are accompanied by substantial impairments in sleep quality and psychosocial functioning. These results highlight the importance of addressing residual symptoms, particularly insomnia and functional difficulties, in long-term management strategies. Interventions aimed at improving sleep and enhancing daily functioning should be considered essential components of treatment to promote recovery and quality of life in remitted patients.
