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

backgroundDogs are a popular pet in many countries, and for them to gain appropriate exercise, many owners opt to walk them on a leash. Despite health and welfare concerns, brachycephalic breeds remain common as pets, with limited research existing that investigates the best restraint type for these animals.

objectivesThis study aimed to test the effect of a collar and harness during stationary and exercise conditions on the intra-ocular pressure (IOP) and respiration rate (RR) of brachycephalic and dolichocephalic dogs.

methodsA total of 24 healthy dogs, both brachycephalic and dolichocephalic, were recruited for the study and underwent stationary and exercise conditions in two restraint types in a within-between-subjects design. IOP was measured by rebound tonometry, and RR was measured using clinical and visual methods by the same experimenter.

resultsJust wearing a collar in a stationary condition increased IOP in brachycephalic dogs (p < 0.05) but not in dolichocephalic dogs (p > 0.05). Exercising in a collar increased IOP for both groups of dogs (p < 0.05), whereas exercising in a harness did not affect IOP for either group (p > 0.05). RR increased in exercise conditions for both restraint types in brachycephalic dogs (p < 0.05), with no difference between collar and harness (p > 0.05).

conclusionsData suggest that collars may elevate IOP during exercise for all dogs and also during stationary conditions for brachycephalic breeds. Owners need to be conscious of the most appropriate restraint for their dog to avoid deleterious effects on IOP and RR.
