Paradoxical relationship between subjective and objective cognition: the role of sleep.

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
STUDY
objectivesSubjective memory complaints and objective cognitive dysfunction are common in aging populations; however, research investigating the associations between them is inconclusive. Given the high prevalence of sleep complaints in middle-aged/older adults, this research tested whether objective cognition interacted with sleep parameters in its associations with subjective cognition.
methodsCognitively healthy adults aged 50+ years completed the Pittsburgh Sleep Quality Index, Cognitive Failures Questionnaire, and cognitive tasks: Stroop, Sternberg, and Posner cueing. Multiple regression and simple slope analyses examined whether objective cognition interacted with sleep parameters in its associations with subjective memory.
resultsStroop performance and sleep (efficiency and disturbances) had interactive associations with Cognitive Failures Questionnaire-memory. Specifically, better Stroop performance (faster reaction time-control trials) was associated with more memory complaints at worst and average but not best sleep efficiency. Additionally, faster reaction time was associated with more memory complaints only for worst sleep disturbance. Similarly, Sternberg performance and sleep (efficiency and disturbances) had interactive associations with Cognitive Failures Questionnaire-memory. Specifically, higher proportion correct was associated with more memory complaints only at worst sleep efficiency and sleep disturbance. Finally, Posner performance and sleep disturbance had an interactive association with Cognitive Failures Questionnaire-memory. Faster exogenous orienting was associated with more memory complaints only for worst sleep disturbance.
conclusionsObjective cognition interacts with sleep efficiency and sleep disturbances in its associations with subjective memory in mid-to-late life. Findings suggest sleep fragmentation plays a role in the discrepant relationship between objective and subjective cognition. Future studies should investigate this relationship in aging populations with sleep disorders and/or cognitive impairments. CITATION: Costa AN, McCrae CS, Cowan N, Curtis AF.
