Comparison of objective and subjective assessments of sleep time in subjects with bipolar disorder.
Article in Journal of affective disorders, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 25 papers, 1 of them a synthesis that pooled it.
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
introductionSleep disturbance is a core feature of bipolar disorder. To date there are a limited number of studies that compare subjective and objective measures of sleep in populations of subjects with mood disorders. This study evaluated the relationship between subjective and objective measurements of total sleep time (TST) in a bipolar type I disorder (BD I) population.
methodsThirty-nine subjects diagnosed with BD I participated in the study. Mood symptoms were assessed via YMRS and IDS-30-C. Subjects wore an actigraph device and maintained a sleep diary for seven consecutive days. Differences between TST as estimated via sleep diaries and actigraphy were calculated.
resultsObjective and subjective measures of TST were significantly correlated (r=0.5151, p=0.0008). Secondary analysis revealed that the severity of depressive symptoms did correlate to this discrepancy (t=2.65, p=0.01). LIMITATIONS: The impact that medications have on the accuracy of TST reported was not investigated. Also, sleep diaries may have acted to prompt subjects to pay closer attention to their sleep habits and therefore more accurately report TST than in the average clinical setting.
conclusionThe results of the current study demonstrate a significant correlation between the estimation of TST as measured objectively via actigraphy and subjectively via sleep diaries in BD patients. Mood symptomotology might impact the accuracy of TST reported. Further study is warranted.
