Longitudinal sleep duration patterns and their association with cognitive decline in older Chinese adults.
Article in Alzheimer's & dementia (Amsterdam, Netherlands). 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
introductionAssociations between sleep duration and cognitive decline are inconsistent, and the value of longitudinal changes versus static measurements remains unclear.
methodsWe identified longitudinal sleep patterns in 4780 older adults from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) using K-means clustering. Linear mixed-effects models and Cox models assessed cognitive decline and incident dementia risk over 10 years.
resultsThe "Consistently Long" pattern showed the fastest cognitive decline ( DISCUSSION: The trajectory of sleep duration, particularly the direction of change, is a powerful correlate of cognitive decline. Monitoring long-term dynamics outperforms static assessments for identifying high-risk older adults.
