Cognitive function, sleep characteristics and their relationship in older adults with insomnia and anxiety.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
To analyze cognitive function, sleep characteristics and the relationship in older adults with insomnia and anxiety. A total of 99 participants were included in this study, including 50 patients with simple insomnia and 49 patients with insomnia combined with anxiety. General demographic information was collected and the degree of cognitive function was assessed using the Montreal Cognitive Assessment Scale (Moca) and the Pittsburgh Sleep Quality Scale (PSQI). All patients were monitored by polysomnography, and polysomnography monitoring parameters were collected. General demographic data, Moca, PSQI and polysomnography monitoring indicators were compared between the two groups. The correlation between cognitive scores and polysomnography monitoring parameters of patients with insomnia and anxiety was analyzed. There was no significant difference in the general demographic information between the two groups (P > 0.05). The total MoCA score and MoCA memory score of patients with insomnia accompanied by anxiety were significantly lower than those with insomnia alone, while their PSQI scores were significantly higher. The wake time after sleep (WASO) monitored by polysomnography was significantly longer than that in patients with simple insomnia disorder, and the duration of N3 and N3% were significantly shorter than that in patients with simple sleep disorder, with statistical significance (P < 0.05). Executive function was positively correlated with N3 duration and N3%, naming function was negatively correlated with N1 duration and N1%, and memory was negatively correlated with wake time after sleep (WASO) in insomnia patients with anxiety, (P < 0.05). Cognitive function and polysomnography sleep were worse in older adults with insomnia and anxiety. Decreased N3 sleep, increased N1 sleep, and increased WASO may be potential biological markers of cognitive decline in older adults with insomnia and anxiety.
