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

BACKGROUND/

objectivesSleep health impacts numerous domains of human health, and sleep deprivation has emerged as a significant public health concern. Multiple types of dietary nutrient supplementation, dietary intake, and the use of nutritional supplements to enhance sleep quality are recognized as effective methods to improve sleep quality.

methodsWe aim to systematically evaluate the efficacy of dietary supplement interventions in sleep quality improvement across populations with sleep disorders and healthy individuals. We conducted a comprehensive literature search across PubMed, Web of Science, CNKI, ScienceDirect, Wiley, and CVIP databases. Sleep evaluation metrics included the Pittsburgh Sleep Quality Index (PSQI), sleep efficiency (SE), sleep latency (SL), total sleep time (TST), wake after sleep onset (WASO), and number of awake after sleep onset (NASO). Meta-analysis procedures were executed in Review Manager 5.3 and Stata 17.0, with heterogeneity quantified via

resultsThis study, in total, included 28 randomized controlled trials. This meta-analysis's results suggest dietary interventions significantly improved sleep outcomes: reduced PSQI (MD: -0.70, 95% CI: -1.37 to -0.03,

conclusionsThese findings suggest that tryptophan, vitamin D, omega-3, zinc, and antioxidants may enhance sleep quality by decreasing SL, and WASO increases SE and extends TST, respectively.
