Retrospective cohort comparison between fluoroscopic and radiograph-only exams for evaluation of gastrostomy and gastrojejunostomy tubes.
Article in Pediatric radiology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundGastrostomy (G) tube or gastrojejunostomy (GJ) tube checks are radiographic procedures that are frequently ordered to confirm tube positioning.
objectiveTo characterize the sensitivity and specificity of radiograph-only examinations and traditional radiologist-performed fluoroscopy exams for G-tube or GJ-tube malposition and other adverse events detectable by imaging. MATERIALS AND
methodsWe performed a retrospective cohort study at a single tertiary pediatric center that included all subjects who underwent G-tube or GJ-tube checks using fluoroscopy or radiograph-only exams between January 1, 2008, and January 1, 2019. Radiograph-only examinations were defined as checks that consist of frontal and lateral abdominal radiographs after injection of contrast through the G-tube or GJ-tube. Fluoroscopy exams were defined as exams performed by a radiologist in the fluoroscopy suite. Radiology reports were evaluated for reported tube malposition and for other adverse events that are detectable by imaging. Clinical notes from the day of the procedure and longer-term clinical follow-up notes were used as a reference standard for adverse events. The sensitivity and specificity of the two procedures were calculated.
resultsA total of 212 exams, including 86 (41%) fluoroscopy exams and 126 (59%) radiograph-only exams, were evaluated. The most common correctly identified adverse event was tube malposition (9 true positives). The most commonly missed adverse event was leakage around the tube (8 false negatives). Fluoroscopy exams had a sensitivity of 100% (6/6; 95% CI: 100%, 100%) and a specificity of 100% (80/80; 95% CI: 100%, 100%) for tube malposition, while radiograph-only exams had 75% sensitivity (3/4; 95% CI: 33%,100%) and 100% specificity (112/112; 95% CI: 100%, 100%).
conclusionsFluoroscopy and radiograph-only exams have similar sensitivity and specificity for detecting G-tube or GJ-tube malposition.
