Regional Variability of Repeat Esophagogastroduodenoscopy Use in the National Veteran Population.
Article in Digestive diseases and sciences, 2017. 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
backgroundEsophagogastroduodenoscopy (EGD) procedures are performed frequently to evaluate gastrointestinal disease and symptoms.
aimTo determine regional practice variability of repeat EGDs in a national population.
methodsThe study sample included US Veterans with an outpatient index EGD from 1/1/2008 to 12/2010. We determined risk of repeat endoscopy from 1/2008 to 10/1/2014. A logistic regression model was used to assess the association between the odds of repeated EGD and patient demographics, ICD diagnostic codes, and geographic region. Multivariable logistic regression was performed to obtain the adjusted odds ratio and predicted probabilities of repeat EGDs by region.
resultsA total of 202,086 patients had an index endoscopy from 1/2008 to 12/2010. Unique patients with an index endoscopy were predominantly male (93.2%), white (72.8%), and on average 61 years. A total of 58,469 patients (28.9%) had one or more repeat EGDs, accounting for 103,253 repeat procedures through 10/2014. ICD-9-CM codes associated with increased risk of repeat procedures were Barrett's esophagus (OR 3.6, 95% CI 3.5-3.7), dysphagia (OR 1.3, 95% CI 1.2-1.3), ulcer (OR 1.3, 95% CI 2.2-2.4), stricture (OR 1.8, 95% CI 1.7-1.9), and esophageal varices (OR 2.8, 95% CI 2.7-3.0). There was a significant difference in the probability of repeat EGD by VA region, with the Midwest region having the highest probability (31.2%) and Southeast the lowest probability (27.3%). This difference would account for 400 more EGD procedures per 10,000 Veterans, after adjusting for patient demographics and diagnosis codes.
conclusionsRegional practice variability accounts for a substantial volume of repeat EGD procedures, regardless of patient characteristics and associated diagnoses.
