Myxoid leiomyosarcoma of the oviduct and uterus in a Cockatiel (Nymphicus hollandicus).
Article in Veterinary medicine and science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
An 11-year-old female cinnamon cockatiel (Nymphicus hollandicus) was presented with a coelomic distention. Dystocia was suspected, given its previous history of a calcium-deficient diet and multiple instances of nonobstructive dystocia. Exploratory coeliotomy revealed a large intraluminal mass extending through the magnum to the uterus (shell gland). Metastasis and multiorgan involvement were not seen. Histopathologically, malignant and invasive fascicles of spindle cells were associated with abundant myxoid matrix and hypocellular areas. Multinucleation, bizarre cells and atypical mitotic figures were prominent. Masson's trichrome staining verified the muscular origin, and the myxoid matrix was demonstrated utilizing Alcian blue. The neoplastic cells exhibited alpha-smooth muscle actin and desmin immunoreactivity and were negative for vimentin. Thus, the patient was diagnosed with oviductal and uterine myxoid leiomyosarcoma (LMS). The patient survived 34 days post-surgery before death associated with suspected enteritis. Myxoid LMS is an extremely rare neoplasm in animals. To our knowledge, myxoid LMS has not been reported previously in pet birds.
