Prognostic Value of Intrarenal Venous Flow Analysis Using Pulsed-Wave Doppler.
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. An erratum has been issued. 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
backgroundThe predictive value of intrarenal Doppler ultrasonography (IRD) analysis using pulsed-wave Doppler for survival in dogs with myxomatous mitral valve disease (MMVD) remains unknown. HYPOTHESIS/
objectivesImpaired IRD indices, such as a high venous impedance index (VII), are associated with a short survival time in dogs with MMVD. ANIMALS: Seventy-one client-owned dogs with MMVD.
methodsProspective cohort study. Dogs diagnosed with various stages of MMVD between July 2019 and February 2024 were enrolled. Echocardiography and an IRD analysis were performed. Resistance index and VII were estimated using the following formula: (maximum flow velocity-minimum flow velocity)/maximum flow velocity from renal interlobar arteries and veins, respectively. Intrarenal venous flow waveforms were categorized into continuous and discontinuous patterns. Discontinuous IRVF pattern is defined as a minimum velocity of 0. The primary endpoint was defined as a composite of cardiac- and renal-related death.
resultsDuring the follow-up period, 18 dogs met the primary endpoint. A multivariable Cox proportional hazard analysis adjusted for the Mitral INsufficiency Echocardiographic score and plasma creatinine concentrations identified VII > 0.37 (hazard ratio, at least 4.62; 95% CI, 1.47-14.56) and discontinuous intrarenal venous pattern (hazard ratio, at least 3.62; 95% CI, 1.22-10.73) as an independent predictors of cardiac- and renal-related death. No association between resistance index and outcomes was observed in the multivariable analysis. CONCLUSIONS AND CLINICAL IMPORTANCE: Worse outcomes in dogs with MMVD could be predicted by an intrarenal venous flow analysis.
