Intra-Esophageal pH Monitoring on Two Consecutive Days in Patients With Gastroesophageal Reflux Symptoms.
Article in Gastroenterology research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 best method to measure the frequency and duration of gastroesophageal reflux is 24-h pH or 24-h pH/impedance monitoring. However, the detection of reflux can vary when measured on different days. Our aim was to evaluate the possibility that the severity of gastroesophageal reflux is different even under similar conditions on two consecutive days.
methodsWe performed a 48-h pH monitoring in 12 subjects, aged 25 - 63 years, who complaint of heartburn and regurgitation, ten with esophagitis and two with non-erosive disease. The pH measurement was conducted at 5 cm from the lower esophageal sphincter. The patients stayed at the Clinical Investigation Ward of the hospital for 48 h. On each day, they consumed a 2,000 calorie diet. The results obtained on the first day were compared with those on the second day.
resultsMean reflux index in the upright position was different between the two days. Results of the pH-monitoring within the 2 h after the meal revealed differences in the number of acidic reflux and reflux index episodes. Three patients had abnormal DeMeester score on one day and normal score on the other day. Considering the upper limit of 6.0% of the test duration with esophageal pH < 4 as indicative of gastroesophageal reflux disease, two patients showed abnormal results on one day and normal results on the other day.
conclusionsThe 24-h pH monitoring, performed on two consecutive days under similar conditions, can lead to different diagnosis of gastroesophageal reflux disease in symptomatic patients.
