Is the Impedance Baseline Helpful in the Evaluation of Globus Patients?
Article in Journal of neurogastroenterology and motility, 2015. 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
BACKGROUND/
aimsGastroesophageal reflux disease (GERD) has been suggested to be responsible for 23-68% of globus cases. The impedance baseline (IB) acquired by 24-hour multichannel intraluminal impedance monitoring has been proven to represent esophageal mucosal integrity. We aimed to investigate whether the IB is helpful for evaluating globus patients.
methodsTwenty-four-hour multichannel intraluminal impedance pH tracings (MII-pH) were evaluated in globus patients. Differences in the IB between the acid reflux, non-acid reflux, and no reflux groups were analyzed. Receiver operating characteristic (ROC) curves were obtained to determine the optimal measurement point from the lower esophageal sphincter (LES).
resultsA total of 62 patients were analyzed. MII-pH showed that acid reflux, non-acid reflux, and no reflux were present in 13, 5, and 44 patients, respectively. The acid reflux group had a significantly lower IB than the other groups at a location 3 cm from the LES. ROC curve analysis revealed that placement at a position 3 cm from the LES resulted in moderate diagnostic accuracy (area under the curve = 0.88). When we set 2500 Ω as the cut-off value for acid reflux at a position 3 cm from the LES, the additional diagnostic yield for acid reflux was increased by 19.4% compared with that obtained by MII-pH.
conclusionsIB is complementary to pH findings enabling identification of a subset of patients with co-existing acid reflux. Catheter place-ment at a location 3 cm from the LES and a cut-off value of 2500 Ω may be reasonable criteria for estimating acid reflux.
