Changes in hepatic and renal Doppler ultrasonography: Current standard therapy in dogs with congestive heart failure.
Article in Open veterinary journal, 2025. 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
Background: In congestive heart failure (CHF), the heart cannot deliver sufficient blood for the metabolic needs of the tissues, leading to vascular changes and organ dysfunction (e.g., kidney and liver). Aim: This study aimed to evaluate the effects of the current standard therapy on kidney and liver hemodynamic changes in dogs with congestive heart failure. Methods: Renal and hepatic Doppler ultrasonography was performed in 15 dogs diagnosed with stage C and D heart failure according to the American College of Veterinary Internal Medicine classification. As a current standard therapy, pimobendan, enalapril, and furosemide were administered to dogs for 4 weeks. Doppler ultrasound findings and serum biochemistry values of the patients were evaluated before and at weeks 1, 2, or 4 of treatment. The control group consisted of 10 healthy dogs. Results: Heart failure was diagnosed in the dogs by an echocardiographic evaluation. The values of hepatic and renal resistive index, renal pulsatility index, and hepatic vein systole-diastole ratio were deteriorated in the dogs with CHF compared with those in the healthy control group ( Conclusion: Doppler ultrasonography findings demonstrated that heart failure worsens the vascular hemodynamics of the kidney and liver in dogs. Congestive heart failure treatment may improve the cardiorenal and cardiohepatic changes due to CHF.
