Prognostic Factors in 26 Cats Undergoing Surgery for Extra-Hepatic Biliary Obstruction.
Article in Veterinary sciences, 2024. 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
Surgical management of feline extra-hepatic biliary obstruction (EHBO) has poor survival rates with few prognostic factors reported in the literature. The etiology and clinical findings of feline EHBO and their influence on short-(2 weeks-6 months) and long-term (>6 months) survival and prognosis were examined in an observational clinical retrospective study of 26 client-owned cats undergoing surgery for biliary obstruction at one institution between 2012 and 2020. The etiology of EHBO was determined in 21/26 cats, which included inflammatory causes (14/21), neoplastic causes (6/21), and a duodenal foreign body (1/21). Pre-operative hyperbilirubinemia and post-extubation hypotension (mean arterial pressure < 60 mmHg) were statistically associated with reduced short- and long-term survival. Short-term survival was documented in 17/26 cats, and long-term survival in 13/26 cats. Median survival time (MST) was 86 days (range, 0-1497). An MST of 17 days (range, 2-520) in cats with malignancies was found compared to an MST of 1165 days (range, 61-2268) in EHBO resulting from inflammatory complexes. Pre-operative hyperbilirubinemia and immediate post-operative hypotension may represent prognostic factors for cats undergoing surgery for EHBO. Cats with inflammatory causes of EHBO carry a more favorable prognosis than neoplastic causes. Further studies are required to evaluate the validity of the observed associations.
