Treatment with vonoprazan for 3 weeks is not inferior to 8 weeks for the management of gastric ESD: a multicenter noninferiority randomized study.
Trial report in Journal of gastroenterology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundVonoprazan, a potassium-competitive acid blocker (VPZ), significantly reduces postoperative bleeding after gastric ESD; however, there is no consensus on the appropriate treatment duration. We conducted a randomized controlled study to demonstrate that the 3-week administration of VPZ is not inferior to the 8-week administration for ulcer healing.
methodsThis is a prospective, open-label multicenter randomized controlled trial. Patients aged 20-85 years undergoing gastric ESD were included in this study. The key exclusion criteria were patients with bleeding tendencies and those taking NSAIDs, steroids, PPIs, or VPZ medications. Eligible patients were randomly assigned to the VPZ 3w or 8w treatment group. The primary endpoint was the proportion of patients with complete closure of the post-ESD wound at 24 weeks after ESD. The key secondary endpoints included the proportion of patients with complete closure of the post-ESD wound at 8 weeks and the proportion of bleeding or perforation more than 3 weeks after ESD.
resultsFrom May 2018 to October 2020, 234 patients were included. The proportion of patients with complete ulcer closure was significantly lower in the 3w group than in the 8w group (70.8% vs. 90.6%) at 8 weeks post-treatment. The complete closure rates at 24 weeks in the 3w and 8w groups were 99.1% and 99.2%, respectively. The absolute difference in the closure rate at 24 weeks was - 0.059% [95% confidence interval (CI) -3.4% to 3.2], and the lower limit of the 95% CI exceeded -10%, the preset threshold. None of the patients developed delayed bleeding 3 weeks after ESD.
conclusionThis multicenter randomized study demonstrated that 3 weeks of treatment with VPZ is sufficient for ulcer healing. Trial registry number. UMIN000031564.
