Outcomes in dogs with congenital extrahepatic portosystemic shunts treated with surgical ligation or medical management.
Article in Veterinary medicine and science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
objectiveThe objective of this study was to evaluate differences in outcomes in dogs treated for extrahepatic portosystemic shunts (EHPSS) by either complete suture ligation, partial suture ligation or medical management. STUDY
designThis wasa retrospective, single institutional study. SAMPLE POPULATION: Dogs (n = 152) with EHPSS treated with suture ligation (n = 62), surgery with no ligation (n = 2), or medical management (n = 88).
methodsMedical records were reviewed for data on signalment, treatment variables, complications, and outcome. Kaplan-Meier plots were generated to assess survival across groups. Cox's proportional hazard models were used to assess the relationship between survival times and multiple predictor variables. For outcomes of interest, backwards, stepwise regression was performed (p < 0.05).
resultsComplete suture ligation was possible in 46/64 (71.9%) of dogs where surgical attenuation was attempted. One dog was euthanized following partial suture ligation due to suspected portal hypertension. Dogs with complete suture ligation of the EHPSS had a significantly longer median survival time (MST) compared to the medical management group (MST not reached vs. 1730 days [p < 0.001]). Complete resolution of clinical signs (without the need for further medical treatment or dietary changes) was achieved in 16/20 (80.0%) dogs with complete suture ligation and 4/10 (40.0%) dogs with partial suture ligation of their EHPSS.
conclusionSuture ligation (complete or partial) for the treatment of EHPSS, where clinically possible, yielded the best clinical outcome and increased longevity compared to medical management in this study. CLINICAL SIGNIFICANCE: While medical management for the treatment of EHPSS in dogs is a valid treatment option, better clinical outcomes are achieved with surgical intervention.
