Factors Affecting Sleep Among Dogs and Cats in a Veterinary Intensive Care Unit.
Article in Journal of veterinary emergency and critical care (San Antonio, Tex. : 2001). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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 evaluate the amount of sleep obtained by hospitalized dogs and cats in an intensive care setting and to identify factors that may impact veterinary patients' sleep.
designA prospective, observational study spanning a 4-week period in June of 2020.
settingAcademic teaching hospital. ANIMALS: A total of 96 dogs and 16 cats hospitalized in the ICU during the 4-week study period.
interventionsNone. MEASUREMENTS AND MAIN
resultsPatient activity was categorized as active, resting, or asleep and was recorded along with ICU environmental data on an hourly basis. Environmental data consisted of subjective assessment of noise level, ambient lighting, number of people present, and number of hospitalized patients. The median observed time asleep was 40% and 11% for dogs and cats, respectively. During natural nighttime hours (9:00 p.m. to 6:00 a.m.), the odds of a patient being asleep were 1.7 times higher if lights were dimmed (p < 0.001). Patients were also less likely to be asleep with higher noise levels (odds ratio 0.66 for each increase in noise level, p = 0.003).
conclusionsHospitalized dogs and cats experience sleep disturbances similar to those reported in human ICU patients. Ambient noise and light are significant factors contributing to sleep disruption in cats and dogs hospitalized in a veterinary ICU. The findings of this study support implementing efforts to promote patient sleep through environmental modifications in the veterinary intensive care setting. Additional research is needed to establish objective means of assessing sleep in hospitalized dogs and cats, to determine sleep patterns of hospitalized veterinary patients, and to quantify the impact of sleep disturbances on veterinary patient convalescence.
