1 · What the graph read from 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.

Abstract

Meditation practice has been shown to impact resting-state EEG activity in expert meditators, but its benefits on sleep, which is particularly affected with age, are poorly understood. Our aim was to better understand the effects of long-term meditation practice on resting-state EEG and sleep in older adults. Twenty-seven elderly expert meditators (mean age ± SD: 70.7 ± 5.0 years) were compared to meditation-naive controls (69.3 ± 3.8 years) for sleep questionnaires (n = 135), polysomnography (n = 47) and resting-state EEG (n = 73). Sleep microstructure (slow waves and spindles) and EEG features (power, Kolmogorov complexity and permutation entropy (PE)) during resting-state, NREM, and REM sleep were compared between groups. Correlations were tested between the metrics that differed between the two groups and the level of meditation expertise within the meditator group. At rest, expert meditators exhibited lower delta power and higher delta PE than controls. Self-reported sleep quality did not differ between groups, but expert meditators slept longer, had reduced %N1, and higher %N2. During NREM sleep, they exhibited reduced delta power, increased alpha power, and greater theta PE. During REM sleep, they tended to show greater theta power. Finally, the composite score of meditation expertise was negatively associated with %N1, and tended to be positively associated with %N2 and REM sleep theta power. Overall, these results suggest that expert meditators showed more preserved brain activity at rest and sleep architecture, and exhibited EEG features suggesting higher cognitive states during NREM sleep.
