Sleep quality impairments in schizophrenia and bipolar affective disorder patients continue during periods of remission: a case-controlled study.

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
Objective: Bipolar disorder (BD) and schizophrenia are chronic psychiatric disorders in which sleep disorders are commonly seen. In mental disorders, residual symptoms may persist even if symptoms are greatly reduced overall. The aim of this study was to compare the sleep quality of schizophrenia and BD patients in remission with that of healthy controls. Methods: Forty-three patients with schizophrenia, 46 BD patients in remission for at least 3 months, and 51 healthy controls were included the study. The Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Young Mania Rating Scale (YMRS) and Pittsburgh Sleep Quality Index (PSQI) were administered to all participants and the Positive and Negative Syndrome Scale (PANSS) was administered to patients with schizophrenia. Results: Poor sleep quality was more frequent in the patient groups than the control group ( Conclusion: Schizophrenia and BD patients in remission had worse sleep quality than a control group. Sleep quality was worst in the patients with schizophrenia. The severity of sleep disorder symptoms was positively associated with disease duration and negatively associated with duration of remission. Schizophrenia and BD patients should be carefully evaluated for symptoms of sleep disorders even when they are in clinical remission and should be offered additional treatment for sleep disorder symptoms when necessary.
