Low plasma butyrylcholinesterase activity in dogs: prevalence, association with underlying disorders, laboratory variables, and survival.
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
backgroundLow blood butyrylcholinesterase (BChE) activity is associated with obesity, pancreatitis, inflammation, sepsis, and malignancy in people, often with negative prognostic value. The clinical relevance of BChE activity in dogs remains unclear. HYPOTHESIS/
objectivesDescribe the prevalence of low BChE activity in a large population of dogs and its association with selected underlying disorders, outcome, and clinicopathological variables. We hypothesized that low BChE activity would be associated with inflammatory disorders and a negative outcome. ANIMALS: A total of 950 client-owned dogs presented to a university teaching hospital with BChE activity measured within 24 h of admission.
methodsRetrospective observational study of clinical records and laboratory data.
resultsAdmission BChE activities ranged from 482 to 17 348 U/L (median, 4553 U/L; interquartile range [IQR], 3485-5926 U/L) and were below reference intervals (RI) in 83 of 950 dogs (8.7%) at admission and in 53 of 207 (25.6%) dogs with repeat in-hospital measurements. Low BChE activity was associated with systemic inflammatory response syndrome (SIRS) and sepsis, but the predictive value was lower than that of C-reactive protein (CRP). Low admission BChE activity was associated with increased odds of non-survival, lower hematocrit and cholesterol concentrations and increased band neutrophil percentages, but no associations were found with obesity, acute pancreatitis, or malignancy. CONCLUSIONS AND CLINICAL IMPORTANCE: Activity of BChE behaves as a negative inflammatory marker in dogs, but its utility as a standalone clinical classifier for SIRS or sepsis is limited and inferior to CRP. Low BChE activity is associated with poor prognosis but is not an independent predictor of outcome.
