Comparison of upper gastrointestinal contrast studies and pH/impedance tests for the diagnosis of childhood gastro-oesophageal reflux.
Article in Pediatric radiology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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
backgroundThe upper gastrointestinal (UGI) contrast study is used in the assessment of children with gastro-oesophageal reflux (GOR) and for detection of structural anomalies. The pH study is more sensitive than the UGI study for the diagnosis of GOR. The pH study has been replaced by the pH/impedance test, which detects both acid and nonacid reflux.
objectiveTo compare the UGI contrast study with the pH/impedance test for the diagnosis of GOR in children. MATERIALS AND
methodsWe retrospectively reviewed consecutive records of children investigated for GOR from October 2008 to February 2010, and compared the findings of UGI studies with those of pH/impedance tests.
resultsThe UGI studies revealed GOR in 116 of 579 children (20%). Of the children undergoing a UGI study, 66 also underwent a pH/impedance test. Using the pH/impedance tests as the reference for GOR, UGI had a sensitivity of 42.8% and a negative predictive value of 24%. There was no significant correlation (P > 0.05) between the reflux index and the number of reflux episodes in the pH/impedance tests and height of reflux in the UGI study. There were low incidences of malrotation (0.9%), hiatus hernia (1%) and delayed gastric emptying (0.4%).
conclusionThe UGI study had low sensitivity for the diagnosis of GOR and low yield for the diagnosis of structural anomalies.
