Sleep and functional capacity in adults: Cross-sectional associations among self-report and objective assessments.
Article in Sleep health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers.
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
objectivesThis study examined the relationship between self-reported and objectively measured sleep and functional capacity in adults.
designCross-sectional.
participantsData were from the Midlife in the United States study. The sample consisted of men and women (n = 664) aged 25-83 who completed telephone interviews, questionnaires, and an overnight clinic stay. MEASUREMENTS: Sleep was assessed by self-report (Pittsburgh Sleep Quality Index [PSQI]) and by objective measures (sleep latency, duration, wake after sleep onset [WASO], and midpoint/midpoint variability) from 7 consecutive days of actigraphy. Functional capacity was assessed by self-report of limitations and measured gait speed, grip strength, and chair stands.
resultsIn linear regression models adjusting for demographic and health factors, better self-reported sleep quality predicted fewer reported limitations, stronger grip, quicker gait, and faster chair stands (all P< .01). Greater WASO predicted more self-report limitations and slower gait speed (P< .05). Long (>8 hours) sleep duration and a more variable sleep schedule predicted lower grip strength (p < .05). Finally, after adjustment for objective sleep measures, PSQI remained a significant predictor of functional measures (P< .05) and explained a significant amount of additional variance (change in R
conclusionsThe present results suggest that subjective and objective sleep measures capture distinct aspects of sleep that are independently related to functional capacity. The variance in functional measures explained by sleep variables, though small, was comparable to other risk factors for functional impairment (eg, obesity), underscoring the importance of associations between sleep and optimal function in adults.
