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

backgroundSelective anthelmintic treatment, advocated due to evolving anthelmintic resistance, has been associated with an increase in Strongylus vulgaris prevalence. Reverting to routine interval anthelmintic treatments is not viable and therefore, identifying other management factors correlated with S. vulgaris infection is vital.

objectivesTo investigate possible risk factors associated with the presence of S. vulgaris infection in resident horses on Swedish horse establishments. STUDY

designInternet-based questionnaire survey.

methodsA questionnaire, created using the internet-based survey platform Netigate, was distributed to owners of equine establishments throughout Sweden via established equine platforms and social media channels. The survey was available for response from 21 May until 1 September 2022. Questions were closed ended with branching logic paths.

resultsFour factors were significantly associated with S. vulgaris infection, with an increased odds of infection seen in livery yards (odds ratio [OR] 1.67, 95% confidence interval [CI] 1.18-2.36, p = 0.004) and premises with more than 10 resident horses (OR 2.42, 95% CI 1.64-3.56, p < 0.001). A lower odds of infection were seen in establishments using quarantine routines (OR 0.69, 95% CI 0.50-0.96, p = 0.03) and anthelmintic treatment of new horses prior to arrival at the premise (OR 0.37, 95% CI 0.18-0.74, p = 0.005). MAIN LIMITATION: Due to the presence of S. vulgaris infection in the present study being based on S. vulgaris diagnostics performed at the farm level, any association between faecal diagnostic use and risk of infection could not be investigated.

conclusionsAlthough the use of diagnostics for S. vulgaris can keep infection rates low, large farms or livery yards with many different horse owners, and those with low use of biosecurity measures as regards to new horses arriving at the premise, are associated with a higher risk of infection.
