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
backgroundMultichannel Intraesophageal Impedance with pH (MII-pH) provides complete characterization of gastroesophageal reflux (GER). The aim of this study was to report our experience in this relatively new technique, emphasizing the challenges in the performance and interpretation of the results.
methodsThe study was conducted at King Khalid University Hospital at King Saud University in Riyadh. A retrospective review of the medical records of children who underwent MII-pH was performed. The procedure was performed and interpreted according to the recommended methodology. The impedance catheter was introduced nasally. The use of event markers and diary were explained to the accompanying person. At the end of the recording, the data were downloaded to the software analysis system.
resultsMII-pH was performed on 98 children, and 16 studies were excluded from analysis for technical reasons. The median age was 32 (range 2-168) months and 44 (54%) were male. The prevalence of nonacid gastroesophageal reflux (NAGER), proximal extent of GER, and postprandial NAGER were 55%, 50%, and 70%, respectively. One hundred and fifty-three symptoms were reported during the study, but only two were significant.
conclusionThe MII-pH was well-tolerated but the performance and interpretation were technically demanding. The main advantage was the detection of NAGER. However, the lack of normal values and the reliance on symptom association make the interpretation of the results challenging.
