Establishing normal values for pediatric esophageal diameter on fluoroscopy.
Article in Pediatric radiology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundStandardized values for esophageal diameter on fluoroscopy have not been established. These values may help in the diagnosis of long-segment and diffuse esophageal narrowing, which can sometimes be subtle and difficult to diagnose.
objectiveOur objective was to establish normal values for esophageal diameter based on age for patients between 1 and 17 years old. MATERIALS AND
methodsOur retrospective study included 160 patients separated into eight groups by age with documented normal upper gastrointestinal fluoroscopic examination and normal esophageal biopsy. Three readers measured esophageal diameters in the three locations and two projections. Intra-class correlation coefficients were calculated in order to gauge reader measurement agreement. Student's t-tests were used to evaluate for statistically significant differences between male and female patients. Finally, overall means and 95% confidence intervals were calculated at each esophageal level by age group.
resultsOur readers demonstrated excellent measurement agreement (ICCs > 0.75). Three individual esophageal measurements varied between the biological sexes, but there was no reliable statistically significant difference. There was a linear upward trend in esophageal diameter with age. For each age group, the means, standard deviations, and 95% confidence intervals were calculated for esophageal diameter in each location and projection. Across all included ages, the mean esophageal diameter ranged from 11-21 mm on the anteroposterior projection and 8-17 mm on the lateral.
conclusionThe provided ranges of normal esophageal diameters at each age and location in the pediatric population are quantitative metrics which can be used in the interpretation of fluoroscopic examinations. New reference values may lead to earlier diagnosis of esophageal pathology in the pediatric population.
