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

backgroundHelicobacter pylori (H. pylori) eradication regimens may have different effects on the gut microbiota. Few studies have analyzed the safety of high-dose dual therapy (HDDT) from a micro-ecological perspective. This study aimed to compare the impact of H. pylori eradication with HDDT and bismuth quadruple therapy (BQT) on gut microbiota. PATIENTS AND

methodsH. Pylori-infected treatment-naive patients were recruited and screened from September 2023 to April 2024 and randomly assigned to the HDDT group (esomeprazole 20 mg, amoxicillin 750 mg, qid, 14 days) or BQT group (esomeprazole 20 mg, amoxicillin 1000 mg, clarithromycin 500 mg, and bismuth potassium citrate 600 mg, bid, 14 days). Fresh stool specimens were collected and stored before treatment and at week 2 and week 8 after treatment. The diversity and composition of the gut microbiota were compared and analyzed in both groups using 16 S rRNA gene sequencing.

resultsForty-nine H. pylori positive patients were enrolled and randomly assigned to either the HDDT (n = 24) or the BQT group (n = 25) group. Compared with baseline, alpha and beta diversities significantly changed at week 2 after receiving BQT and did not recover fully at week 8. However, in the HDDT group, the diversities at week 2 changed mildly without statistical significance, compared to baseline. Additionally, a greater number of species had alterations in their abundances in the BQT group compared to the HDDT group at week 2. However, the abundances of these species were restored to their previous levels at week 8 in both the HDDT and BQT groups.

conclusionsCompared to BQT, HDDT exerted less impact on the diversity and composition of the gut microbiota. CLINICAL
