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.

2 · The registry

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

objectiveTo explore the associations of Physical Activity (PA) and sleep with functional disability among older adults.

methodA total of 1927 participants were enrolled from the China Health and Retirement Longitudinal Study (CHARLS) between 2015 and 2020. Activities of Daily Living (ADL) were used to assess functional status. Sleep consisted of nighttime sleep (healthy sleep, or unhealthy sleep) and daytime nap sleeping (extended, moderate, short, or none), and PA was classified as sufficient or insufficient. Effects of sleep and PA on ADL Disability (ADLD) among the elderly were examined using logistic regression analysis, with Odds Ratios (ORs) and 95% Confidence Intervals (95% CIs) calculated.

resultsAfter a follow-up of 5-years, healthy nighttime sleep was linked to a decreased odds of ADLD (OR = 0.77, 95% CI: 0.60‒0.98). In participants with sufficient PA, healthy nighttime sleep was linked to the odds of ADLD (OR = 0.68, 95% CI: 0.52‒0.90). No multiplicative interaction of PA and nighttime sleeping was found. Moreover, the association between healthy nighttime sleep and decreased risk of ADLD was consistent in females (OR = 0.64, 95% CI: 0.45‒0.91) and those with complications (OR = 0.63, 95%CI: 0.46‒0.87).

conclusionHealthy nighttime sleep may be beneficial for preventing ADLD in older people. The benefits of sufficient PA with healthy sleep on reducing the risk of ADLD remain uncertain.
