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

backgroundBed sharing is common practice across the global population. However, the vast majority of research on bed sharing has focused solely on mother-infant bed sharing.

methodsHere, we provide a holistic review of research on bed sharing. Articles investigating the relationship between bed sharing and sleep were identified in 4 dyad categories: (1) parent and child, (2) couples, (3) siblings, and (4) pet owners and pets. Of interest was whether sleep-promoting factors such as psychological comfort were generalizable across bed-sharing dyads; alternatively, sleep-demoting factors such as movement or heat may be commonalities.

resultsWe found that, across dyad types, in general, subjective reports of sleep quality were better when bed sharing despite generally worse objective measures of sleep.

conclusionsUnderstanding bed sharing is important to treating sleep disturbances, given the prevalence of shared beds. This scoping review points to critical gaps in our understanding of bed sharing that motivate future research.
