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

backgroundBreed predispositions for bacterial hepatobiliary infections have not been established. HYPOTHESIS/

objectivesTo determine prevalence of bacterial hepatobiliary infections in dogs presenting to referral hospitals in the United Kingdom, ascertain whether specific breed predispositions exist, and to identify associated bacterial species. ANIMALS: One hundred twenty-six client-owned dogs diagnosed with bacterial hepatobiliary infections from 3 referral centers in the United Kingdom from a denominator cohort of 71 036 dogs.

methodsRetrospective multicenter study. Prevalence of dogs diagnosed with bacterial hepatobiliary infections was calculated. Odds ratios were calculated to establish breed predispositions. Signalment, clinicopathologic results, imaging abnormalities, bacterial culture results, gallbladder histology, treatment, and outcomes were reported.

resultsOverall prevalence was 0.15% (95% CI, 0.12-0.18). Miniature Schnauzers (OR 8.95, 95% CI, 4.36-18.35, P < .0001) and Border terriers (OR 3.21, 95% CI, 1.06-9.70, P = .04) were predisposed for bacterial hepatobiliary infection compared to crossbreed dogs. Escherichia coli (70/156, 44.9%) and Enterococcus species (26/156, 16.7%) were the most frequently cultured isolates. More than 1 isolate was cultured in 33 out of 114 (28.9%) dogs. Of isolates with available susceptibility data, 55 out of 123 (44.7%) were multidrug resistant (MDR); 36 out of 123 (29.3%) were resistant to at least one fluoroquinolone, and 20 out of 123 (16.3%) were resistant to amoxicillin-clavulanate when first detected. CONCLUSIONS AND CLINICAL IMPORTANCE: Breed predispositions for bacterial hepatobiliary infections have been identified for Miniature Schnauzers and Border terriers. A notable proportion of bacterial isolates were MDR at first detection, but most were susceptible to amoxicillin-clavulanate.
