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

backgroundMiddle ear abnormalities are frequently observed in brachycephalic dogs due to their anatomical variation, and the prevalence of these abnormalities may be influenced by modern breed popularity. HYPOTHESIS/

objectivesWe hypothesized that 10% of dogs with signs of neurologic disease will have incidental otitis media (OM) and that brachycephalic breeds will have a higher occurrence of OM. ANIMALS: Three hundred eighty client-owned dogs that underwent magnetic resonance imaging (MRI) of the head for any signs of neurologic disease.

methodsRetrospective, single-institution study. Prevalence of any kind of otitis and association with dog clinical signs were analyzed using standard multinomial formulas and Fisher's exact test. Signalment variables with P-values less than .1 but with no zero counts on bivariable analysis were included in a multivariable logistic regression model. Statistical significance was set to P < .05.

resultsOf the dogs in this study, 60 (15.7%) had otitis of any kind. Among these, 15 (3.9%) were diagnosed with otitis of any kind as the primary cause of their clinical signs, all of which were affected by OM and all but one had otitis interna (OI). Forty-five (45/380, 11.8%) were classified with incidental otitis of any kind. The most common form of otitis was OM in 54 dogs (54/380, 14.2%). French Bulldogs were the most common breed reported (32/380, 8.4%) and 18 (56%) had evidence of 1 or more types of otitis: 5 causative and 13 incidental. CONCLUSION AND CLINICAL IMPORTANCE: Otitis media is commonly an incidental finding in dogs undergoing MRI of the head, especially in brachycephalic breeds. French Bulldogs are more frequently affected. These findings can help guide diagnostic and treatment approaches for dogs with neurologic disease.
