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

backgroundSleep disorders are problems that include both the quality and the time of sleep. It is related to overall diet quality, and dietary patterns also affect the quantity and quality of sleep in humans. The Healthy Eating Index (HEI) is widely used to assess the quality of diet. Epidemiological studies have investigated the association between diet quality and sleep, but these associations have not been confirmed in meta-analyses. A meta-analysis was performed to analyze whether there was an association between sleep disorders and HEI.

methodsA comprehensive search of several databases, including PubMed, Cochrane, Medline, Web of Science, and EMBASE, was conducted to identify relevant available studies reporting the relationship between sleep quality, abnormal sleep time, and HEI. Study results were meta-analyzed using the odds ratios (ORs) and their 95% confidence intervals (95% CIs).

resultsA total of five observational studies were involved in the final analysis. Meta-analysis showed that higher HEI scores are associated with lower risk of poor sleep quality (OR = 0.860; 95% CI, 0.743-0.997; p = 0.045). The higher the HEI scores, the lower the risk of abnormal sleep time (OR = 0.296; 95% CI, 0.088-0.987; p = 0.048).

conclusionThe higher HEI score is associated with good sleep quality and a reduced risk of abnormal sleep time.
