Videofluoroscopic swallow study features of lower esophageal sphincter achalasia-like syndrome in dogs.
Article in Journal of veterinary internal medicine, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundMegaesophagus (ME) carries a poor long-term prognosis in dogs. In people, lower esophageal sphincter (LES) disorders causing functional obstruction are rare causes of ME that may respond to targeted treatment. Functional LES disorders are reported rarely in dogs because of challenges in diagnostic methodologies. HYPOTHESIS/
objectivesTo identify dogs with videofluoroscopic swallow study (VFSS) features of LES achalasia-like syndrome (LES-AS). We hypothesized that dogs with LES-AS could be distinguished from normal dogs using standardized VFSS criteria. ANIMALS: Dogs with LES-AS by VFSS (n = 19), healthy normal dogs (n = 20).
methodsRetrospective study. One-hundred thirty dogs presented to the University of Missouri Veterinary Health Center (MU-VHC) between April 2015 and December 2017 for a free-feeding VFSS; 20 healthy dogs were included as controls. Swallow studies were evaluated for failure of the LES to relax during pharyngeal swallow (LES-AS). Affected dogs subsequently were evaluated using standardized criteria to identify metrics important for identifying and characterizing dogs with LES-AS.
resultsNineteen dogs with LES-AS were identified out of 130 VFSS. Megaesophagus was present in 14 of 19 (73.7%) dogs with LES-AS. A baseline esophageal fluid-line and "bird beak" were present in 68.4% (95% confidence interval [CI], 47.5%-89.3%) and 63.2% (95% CI, 41.5%-84.8%) of affected dogs, respectively. The esophagus was graded as acontractile (8/19), hypomotile (8/19), or hypermotile (3/19). CONCLUSIONS AND CLINICAL IMPORTANCE: Dogs with LES-AS may successfully be identified by VFSS using a free-feeding protocol. These data are of critical clinical importance because a subpopulation of dogs with functional LES obstruction may be candidates for targeted intervention.
