Control of acid and duodenogastroesophageal reflux (DGER) in patients with Barrett's esophagus.
Article in The American journal of gastroenterology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectivesSymptom eradication in patients with Barrett's esophagus (BE) does not guarantee control of acid or duodenogastroesophageal reflux (DGER). Continued reflux of acid and/or DGER may increase risk of neoplastic progression and may decrease the likelihood of columnar mucosa eradication after ablative therapy. To date, no study has addressed whether both complete acid and DGER control is possible in patients with BE. This prospective study was designed to assess the effect of escalating-dose proton pump inhibitor (PPI) therapy on esophageal acid and DGER.
methodsPatients with BE (≥3 cm in length) underwent simultaneous ambulatory prolonged pH and DGER monitoring after at least 1 week off PPI therapy followed by testing on therapy after 1 month of twice-daily rabeprazole (20 mg). In those with continued acid and/or DGER, the tests were repeated after 1 month of double-dose (40 mg twice daily) rabeprazole. The primary study outcome was normalization of both acid and DGER. Symptom severity was assessed on and off PPI therapy employing a four-point ordinal scale.
resultsA total of 29 patients with BE consented for pH monitoring, of whom 23 also consented for both pH and DGER monitoring off and on therapy (83% male; mean age 58 years; mean body mass index 29; mean Barrett's length 6.0 cm). Median (interquartile range) total % time pH <4 and bilirubin absorbance >0.14 off PPI therapy were 18.4 (11.7-20.0) and 9.7 (5.0-22.2), respectively. In addition, 26/29 (90%) had normalized acid and 18/23 (78%) had normalized DGER on rabeprazole 20 mg. Among those not achieving normalization on 20 mg twice daily, 3/3 (100%) had normalized acid and 4/5 (80%) had normalized DGER on rabeprazole 40 mg twice daily. All subjects had symptoms controlled on rabeprazole 20 mg twice daily. Univariate analysis found no predictor for normalization of physiologic parameters based on demographics.
conclusionsSymptom control does not guarantee normalization of acid and DGER at standard dose of twice-daily PPI therapy. Normalization of acid and DGER can be achieved in 79% of BE patients on rabeprazole 20 mg p.o. twice daily, and in the majority of the remainder at high-dose twice-daily PPI. In patients undergoing ablative therapy, pH or DGER monitoring may not be needed to ensure normalization of reflux if patients are treated with high-dose PPI therapy.
