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

BACKGROUND AND

aimsPatients that have failed therapy for Helicobacter pylori (H. pylori) infection are incompletely characterized. The aim of this study was to characterize a H. pylori treatment resistant cohort compared to the cohorts of newly diagnosed, earlier eradicated and non-infected. MATERIAL AND

methodsPatients were selected from routine referrals to the Endoscopy units at three different Norwegian hospitals. In all four cohorts, gastric biopsies were scored according to the Sydney classification, and symptoms according to the Gastrointestinal Symptom Rating Scale score, including sub-scores for upper gastrointestinal symptoms and functional bowel symptoms. Patients in the H. pylori resistant group were treated with a triple therapy regimen that consisted of levofloxacin, amoxicillin and a proton pump inhibitor.

resultsWe included 185 patients, 42 H. pylori treatment resistant, 50 newly diagnosed, 61 previously H. pylori eradicated and 32 never infected. The treatment-resistant cohort had higher scores for upper gastrointestinal symptoms and functional bowel symptoms compared to the other groups except for the group being never H. pylori infected. The H. pylori resistant patients had lower Sydney scores than patients with newly diagnosed H. pylori infection. The triple combination showed a high efficacy of 91% to eradicate H. pylori.

conclusionsPatients with treatment-resistant H. pylori infection had more gastrointestinal symptoms, but a lower Sydney score than patients with newly diagnosed infection. A treatment regimen including levofloxacin showed a high efficacy in eradicating H. pylori in patients that previously had failed eradication treatment.
