Multichannel intraluminal impedance-pH testing is clinically useful in the management of patients with gastroesophageal reflux symptoms.

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 intraluminal impedance-pH testing (MII-pH) allows for the detection of acid and non-acid reflux, thus, increasing yield over pH testing. Limited data exist on how physicians use test results in practice.
aimThe aim of our study was to evaluate the influence of MII-pH testing on patient care.
methodsWe reviewed records of patients with symptoms of gastroesophageal reflux disease who underwent MII-pH testing. Management decisions evaluated included changes in prescribed medications and surgical consultation for anti-reflux surgery. Statistical analysis was performed using Pearson Chi square test, and multivariable logistic regression.
resultsMII-pH testing resulted in a medication change in 41% of patients, surgical consultation in 19.7%, and anti-reflux surgery in 11.1%. In patients who were not on proton pump inhibitor (PPI) therapy, MII-pH results were most useful in the decision to start a PPI. On PPI therapy, results were more often used to decide whether to increase (32.3%) or switch the PPI (23.5%) in patients with continued acid reflux. Results were most useful to stop the PPI in normal studies (11.1%). More patients with non-acid reflux (14.3%) and normal results (19.7%) were started on a neuromodulator compared to other diagnoses. The MII-pH result was most useful in the decision to start baclofen or bethanecol when the patient was found to have non-acid reflux (25%). Patients with an abnormal MII-pH or abnormal MII alone were more likely to be referred to surgery (OR 19.5, p < 0.001; OR 19.77, p < 0.001).
conclusionsMII-pH testing impacted medical or surgical management in over half the patients tested.
