Zenker's Diverticulum in Forestier Disease: Chance or Causality?
Article in Iranian journal of otorhinolaryngology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: Zenker's diverticulum is an acquired sac-like outpouching of the mucosa and submucosa layers originating at the pharyngoesophageal junction. The predominant symptom of Zenker's diverticulum is dysphagia. Videofluoroscopy confirms the diagnosis. Forestier disease is a clinical entity characterized by ossification of anterolateral vertebral ligament and anterior osteophyte formation along the anterolateral spinal column. Its etiopathogenesis remains unknown and common symptoms are dysphagia, dysphonia and airway obstruction. The objective of this study is to identify a pathophysiological correlation between Forestier disease and the onset of Zenker's diverticulum. Materials and Methods: A retrospective observational study was conducted. The electronic database of our Radiology Unit was analyzed in order to identify patients with hypopharyngeal diverticulum and osteophytes at the cervical vertebrae level, from January 2010 to January 2021. The search was performed using precise keywords. Results: The computerized database search outlined 10 imaging exams: 5 videofluorographies and 5 computed tomography scans. In 100% of the cases, dysphagia was the main symptom that led to the diagnostic assessment; 30% of patients, on the other hand, reported dyspnoea. From the data analysis, the male / female ratio is 1: 1 and the average age of the patients is 64.8 (+/- 11.31) years. Conclusions: We assume that the anatomical abnormalities in Forestier disease may cause an increase of pharyngeal pressure and consequently support the development of the Zenker's diverticulum. Hence, it is always recommended to investigate the presence of Zenker's diverticulum in a patient with Forestier disease, especially for the life-threatening complications of Zenker's diverticulum.
