Long-term outcomes of dogs with W-shaped or traditional tracheal collapse treated with a continuous extraluminal tracheal prosthesis: A retrospective study.
Article in Veterinary surgery : VS, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveTo report the clinical characteristics of traditional (TTC) and W-shaped tracheal collapse (WTC) and the long-term outcomes of continuous extraluminal tracheal prosthesis (CETP) placement in dogs with grade IV tracheal collapse (TC). STUDY
designRetrospective case series. ANIMALS: A total of 69 client-owned dogs.
methodsMedical records of dogs with grade IV TC, subclassified as TTC or WTC, treated using CETP between 2018 and 2021, were retrospectively reviewed. Clinical signs, diagnostic results, intraoperative findings, surgical complications, and clinical outcomes were analyzed.
resultsOf the 69 dogs, 45 had TTC and 24 had WTC. All were discharged after CETP placement. Preoperative stridor (p < .0001) and labored breathing (p = .0419) were more prevalent in patients with WTC than in those with TTC. The WTC group was 12.1 times more likely to require preoperative oxygen management than the TTC group (OR, 95% CI: 3.2-37.5). The 36-month postoperative survival rates were 75.7% and 90.9% in dogs with TTC and WTC, respectively. Postoperative laryngeal paralysis occurred in three dogs in the TTC group and two in the WTC group. Recurrent TC occurred in one dog in the TTC group and two in the WTC group. Seven of the eight dogs with postoperative complications required surgical intervention or intraluminal stent placement.
conclusionAlthough dogs with WTC showed more severe preoperative respiratory symptoms, their postoperative outcomes were comparable with those of dogs with TTC. CLINICAL SIGNIFICANCE: CETP placement is a viable surgical treatment option for dogs with WTC, even those with severe respiratory symptoms.
