Reference Values and Association of Body Weight, Age, and Sex With Echocardiographic Measurements in Non-Athletic Quarter Horses.
Article in Journal of veterinary internal medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundEchocardiographic reference intervals for Quarter Horses are infrequently reported.
objectivesTo provide standard echocardiographic measurements for sedentary Quarter Horses and evaluate the relationship between physical characteristics (body weight, age, sex) and echocardiographic measurements. ANIMALS: Forty-one sedentary Quarter Horses, free of cardiac disease, from a university research herd.
methodsA cross-sectional study evaluating standardized echocardiograms performed on sedentary Quarter Horses (41) between 2020 and 2022. Reference intervals were calculated for raw and weight-corrected values. Multiple linear regression was performed to evaluate the relationship between the physical characteristics (body weight, age, sex) and echocardiographic variables.
resultsMultiple linear regression showed that every 100 kg of body weight was associated with a 3 (95% CI 1-6) mm thicker left ventricular free wall in systole (p = 0.02), an 8 (95% CI 2-13) mm larger left atrial diameter (p < 0.01), and a 4 (95% CI 0-9) mm larger pulmonary artery diameter (p = 0.04). Every year in age was associated with a 0 (95% CI 0-1) mm larger left atrial diameter (p = 0.02), a 0 (95% CI 0-1) mm larger aortic diameter (p = 0.01), and a 0 (95% CI 0-1) mm larger pulmonary artery diameter (p = 0.01). Left atrial to left ventricular ratio was 1 (95% CI -1 to 0) mm smaller in geldings compared to mares (p = 0.03). CONCLUSIONS AND CLINICAL IMPORTANCE: This study provides echocardiographic reference intervals for a cohort of sedentary Quarter Horses and clarifies the association with body weight, age, and sex with these variables.
