Sleep Disturbance in People with Anxiety or Depressive Disorders over 30 Years, and the Influence of Personality Disorder.
Article in Behavioral sleep medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesSleep disturbance is commonly reported by people with anxiety, depressive, and personality disorders, but longitudinal studies exploring the interplay of the three with disturbed sleep have not previously been described.
methodsIn this study, sleep disturbance was examined among 89 patients initially presenting with anxiety or depressive disorders who provided follow-up at 12- and 30-year time points in the Nottingham Study of Neurotic Disorder. Multilevel models were used to identify factors most predictive of changes in sleep quality over time.
resultsThere were strong associations between poor sleep and contemporaneous severity of personality disorder and the presence of other mental disorders at 12 and 30 years follow-up, but not with disorder presence at other time points. Improvements in personality disorder were associated with improvements in sleep between time points and attenuated the positive unadjusted effects of recovery from anxiety or depressive disorders to non-significance. Relapse into further episodes of mental disorder predicted poorer sleep, whereas worsening personality disorder was not predictive of significant changes when adjusting for other factors.
conclusionsThis study demonstrates the complex interplay between anxiety, depressive, and personality disorders and sleep disturbance over a long follow-up period. Future research might look to examine the relationship between personality disorder and disturbed sleep with interventional studies and by integrating personality trait research.
