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

backgroundVery little is known about sleep disturbances in horses, although several management or animal-based factors may contribute to an increased risk of disturbances.

objectivesTo investigate factors related to rest and sleep behaviour of horses kept in stalls as perceived by Nordic horse owners or caretakers and their association with suspected sleep disturbances (SSD). STUDY

designCross-sectional survey.

methodsThe 40 question online international survey included a convenience sample of horse owners or caretakers with horses over 4 years old kept in the same individual stalls for at least the last three previous months. Multivariate binary logistic regression was used to generate models of the factors associated with the SSD and their possible causes and consequences for the horses.

resultsOverall, 5.0% of respondents (88/1749) suspected that their horse had sleep disturbances. The horse-specific factors which were associated with SSD (adjusted OR; 95% CL) were age in years (1.12; 1.07-1.16), withers height (1.05; 1.03-1.08), current illness/injury (3.14; 1.92-5.15), if the horse was not seen laying down (27.82; 8.72-88.75), nightly injuries (9.16; 3.36-25.00), loss of balance/unexpected fall (40.30; 16.77-96.87), daytime drowsiness (3.85; 1.68-8.82) and difficulties lying down/getting up (16.33; 6.02-44.30). The environment-specific factors associated with SSD were hard and dry (3.50; 1.56-7.84) and hard and wet (8.63; 2.41-30.94) lying surface. MAIN LIMITATIONS: Self-selection enrolment of participants may limit the generalisability of the findings.

conclusionsSeveral environmental and horse-related factors were found to be associated with SSD in horses, including hard and dry/wet lying surfaces.
