The association between sleep quality and cognitive function in patients with non-functioning pituitary adenoma.
Article in Endocrine connections, 2025. 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
Background: Cortisol and growth hormone are important for sleep regulation and cognition. Sleep is critical for cognitive functioning and memory consolidation. Patients with pituitary disease experience hormonal dysregulation, impaired sleep quality, and cognitive dysfunction. We wished to examine the relationship between objective sleep and cognitive functioning in patients with pituitary adenomas. Methods: Ten patients with non-functioning pituitary adenomas (NFPA) and ten healthy controls were assessed using a crossover design. Each participant was administered standardised neuropsychological tests (Wechsler logical memory test (LMT) and finger tapping task (FTT)) assessing declarative and procedural memory performance after a period of sleep and after an equivalent period of wakefulness. Objective sleep data were elicited, and the Pittsburgh Sleep Diary captured self-reported sleep data. Results: Controls performed better than patients with NFPA on retention on the LMT (P = 0.027). Objective measures of sleep quality revealed no between-group differences, whereas controls reported better subjective sleep quality (P = 0.016) and being more alert when awake (P = 0.015) than patients. Generally, sleep was not related to cognition in either group. Conclusions: Patients demonstrated poorer performance on declarative memory tasks, but not poorer sleep. Interventions for memory rehabilitation may assist their capacity to complete other important daily activities.
