Evaluation of the Correlation of Arterial and Venous Lactate and Glucose Concentrations in Anesthetized Critically Ill Dogs.
Article in Journal of veterinary emergency and critical care (San Antonio, Tex. : 2001). 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
objectiveTo investigate the correlation between arterial and venous concentrations of lactate and glucose and to explore the relationship between hyperlactatemia and hyperglycemia in critically ill dogs.
designProspective clinical study.
settingUniversity veterinary teaching hospital. ANIMALS: Ninety client-owned dogs presenting for emergency surgery between June 2015 and March 2024.
interventionsNone. MEASUREMENTS AND MAIN
resultsArterial and venous blood samples were collected from the dorsal pedal artery and jugular vein, respectively, ≤5 min apart to measure lactate and glucose concentrations with portable devices. Dogs with known diabetes mellitus were excluded. Based on arterial blood, 35 of 90 dogs (38.9%) were hyperlactatemic, 49 (54.4%) were hyperglycemic, and 9 (10.0%) were hypoglycemic. Based on venous blood, 41 of 90 dogs (45.6%) were hyperlactatemic, 46 (51.1%) were hyperglycemic, and 8 (8.9%) were hypoglycemic. A very strong correlation was found between arterial and venous lactate and glucose concentrations (ρ = 0.850; 95% confidence interval [CI]: 0.766-0.905; p < 0.001 and ρ = 0.970; 95% CI: 0.950-0.982; p < 0.001, respectively). In dogs with arterial hyperlactatemia, a very strong correlation was found between arterial and venous samples (ρ = 0.835; 95% CI: 0.683-0.918; p < 0.001), whereas the correlation was fair in normolactatemic dogs (ρ = 0.488; 95% CI: 0.224-0.685; p < 0.001). The sensitivity and specificity of venous lactate to detect arterial hyperlactatemia were 81.8% and 88.6%, respectively. No correlation was found between arterial lactate and glucose concentrations (ρ = -0.57; 95% CI: -0.261 to -0.152; p = 0.593).
conclusionsVenous lactate and glucose concentrations correlated well with arterial values; however, hyperlactatemia was not correlated with hyperglycemia. Venous blood sampling offers a practical and reliable method for assessing lactate and glucose concentrations in critically ill dogs, reducing the need for arterial sampling in emergency situations.
