1 · What the graph read from it

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.

2 · The registry

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 currently recommended quadruple regimens as rescue therapy on Helicobacter pylori infection were not as effective as being supposed, especially in those who had failed two or more times. Dual regimen composed of vonoprazan (a potassium-competitive acid blocker) and amoxicillin might be an option since it's effective in eradication therapy as first-line treatment.

objectiveAs a real-world retrospective study, data were collected to evaluate the efficacy and safety of vonoprazan and amoxicillin dual regimen as rescue therapy in Helicobacter pylori positive patients who had failed one or more times in their previous treatment.

methodsFrom May 2020 to June 2021, the clinical data of patients who had failed in Helicobacter pylori infection treatment were collected in GI department of Peking University First Hospital, Beijing, China. Patients were given vonoprazan 20 mg or 40 mg per day and amoxicillin 3000 mg per day (VA dual therapy) for 14 days as rescue treatment. Helicobacter pylori status was evaluated by

resultsA total of 186 patients were enrolled, including 67 males and 119 females. All of them had failed for 1 ~ 7 times in their previous treatment. Successful eradication was achieved in 172 patients (92.5%, 172/186). The adverse effects (referring to skin rash, abdominal pain, diarrhea, and headache), mainly mild and did not cause quit of treatment, occurred in 14 patients (7.5%, 14/186) and all symptoms relieved spontaneously.

conclusionsDual regimen composed of vonoprazan and amoxicillin for 14 days was effective and safe as rescue therapy in Helicobacter pylori infection treatment. It could be chosen as a "simplified rescue therapy" with relatively high eradication rate no matter how many times the patients had failed and what regimens they had used previously.
