Videofluoroscopic swallow study abnormalities identify aerodigestive disorders in dogs with respiratory disease versus healthy controls.
Article in Journal of veterinary internal medicine. 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
backgroundAerodigestive diseases (AeroD) pathologically link respiratory and alimentary tracts. Dogs with respiratory signs lacking dysphagia, vomiting, or regurgitation typically do not undergo diagnostic testing that identifies comorbid alimentary disease. A videofluoroscopic swallow study (VFSS) identifies defects in swallowing, reflux, and aspiration. OBJECTIVES/HYPOTHESIS: We hypothesized that dogs with respiratory and no alimentary disease (RESP) would have significantly more abnormal VFSS metrics versus controls (CON). We hypothesized RESP dogs with pulmonary parenchymal disease would have more reflux and higher penetration-aspiration score (PAS) than those with airway disease. ANIMALS: Client-owned dogs: RESP (n = 45) and CON (n = 15) groups.
methodsProspectively, all dogs underwent VFSS. The RESP dogs had advanced respiratory diagnostic testing. Eight subjective and 3 objective VFSS metrics (pharyngeal constriction ratio [PCR], PAS, and esophageal transit time [ETT]) were assessed. Fisher's exact test compared differences between groups (presence or absence of VFSS abnormalities). The Mann-Whitney rank sum test was used to compare PCR and PAS.
resultsSubjective VFSS abnormalities were present in 34/45 (75%) RESP and 2/15 (13%) CON dogs, with RESP dogs significantly more likely to have VFSS abnormalities (P = .01). No difference in PCR was found between groups. Pathologic PAS was more common in RESP than CON dogs (P = .03). The RESP dogs with airway disease had higher PAS than CON dogs (P = .01) but not RESP dogs with parenchymal disease (P = .25).
conclusionsMost (75%) RESP dogs had VFSS abnormalities, emphasizing that AeroD are common. The VFSS has value in diagnostic evaluation of respiratory disease.
