Seroprevalence of Sarcocystis neurona and Neospora hughesi in healthy horses from the province of Alberta, Canada.
Article in Journal of veterinary internal medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundLiterature on the seroprevalence of antibodies to the causative agents of equine protozoal myeloencephalitis (EPM) in Canada is limited. HYPOTHESIS/
objectivesTo determine the prevalence of serum antibodies against Sarcocystis neurona and Neospora hughesi in apparently healthy horses without signs of neurologic disease which have always resided in Alberta, Canada, using commercially available immunodiagnostic tests. ANIMALS: Samples from 116 healthy horses were obtained from a biobank containing horse serum collected across Alberta in 2021 and 2022. Samples were selected based on owner survey responses, and only horses that had always resided in Alberta were included in the study.
methodsThis cross-sectional study analyzed serum samples for anti-S neurona (SarcoFluor and rSnSAG2/4/3 ELISA) and N hughesi (NeoFluor and NhSAG1 ELISA) antibodies. A subset of 30 samples underwent additional testing by S neurona western blot.
resultsFor anti-S neurona antibodies, 26/116 horses were positive on indirect fluorescent antibody test (IFAT), 4/116 on ELISA, and 5/30 on western blot; however, none of the horses were positive on all 3 of the tests. For anti-N hughesi antibodies, 18/116 were positive on IFAT and 2/116 on ELISA, with no horses positive on both tests. CONCLUSIONS AND CLINICAL IMPORTANCE: These findings suggest possible exposure of Alberta horses to S neurona and N hughesi. However, the commercially available tests had low sensitivities and poor agreement in this study group of apparently healthy horses.
