Characteristics of proton pump inhibitor-resistant severe reflux esophagitis and efficacy of vonoprazan in elderly (older than 75 years) and non-elderly groups.

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 and Aim: Previous studies on age differences in proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) have found that stenosis and bleeding complications were significantly more common in the elderly than in the non-elderly. We sought to examine differences between two groups of elderly (75 years or older) and non-elderly (<75 years) patients with (PPI)-resistant severe RE and also the efficacy of vonoprazan (VPZ) in these patients. Methods: There were 14 patients in the elderly group and 15 in the non-elderly group. Information was obtained on patient background (sex, body mass index [BMI], gastric mucosal atrophy, and the presence of hernia and collagen disease), and all patients underwent the saliva secretion test and esophagogastroduodenoscopy (EGD). The saliva secretion test (amount of saliva secreted, salivary pH, and the acid-buffering capacity) was performed by chewing sugar-free gum for 3 min before EGD. The efficacy of VPZ in both groups was also assessed. Results: Saliva secretion, sex, BMI, and the presence of gastric mucosal atrophy did not significantly differ between the two groups. The number of hernias larger than 4 cm was significantly higher in the elderly PPI-resistant group, and significantly more patients had collagen disease in the non-elderly group. The efficacy of VPZ was not significantly different between the two groups; however, 10 patients in the non-elderly group had collagen disease, and 4 did not achieve esophageal mucosal healing even with VPZ 20 mg. Conclusion: The number of large hernias (>4 cm) was significantly higher in the elderly group, while significantly more non-elderly patients had collagen disease. In the non-elderly group with scleroderma, the efficacy of VPZ 20 mg may not be sufficient.
