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

objectiveTo investigate levels of epidermal growth factor (EGF) and prostaglandin E2 (PGE2) in Han Chinese patients with Helicobacter pylori-positive gastric low-grade intraepithelial neoplasia (LGIN).

methodsIn this prospective, observational study, gastric specimens from patients with LGIN were collected by gastroscopy with consecutive biopsy. EGF and PGE2 concentrations in serum and gastric juice from patients with LGIN were measured by enzyme-linked immunosorbent assay. Presence of H. pylori infection was assessed in patients with LGIN and healthy controls.

resultsOut of 5 638 patients and 548 controls, H. pylori infection in patients with chronic gastritis was associated with disease type (endoscopic classification) and disease severity. Patients with H. pylori-positive LGIN had significantly higher concentrations of serum EGF and lower concentrations of serum PGE2 versus patients with H. pylori-negative LGIN. Serum EGF and PGE2 levels in patients with LGIN were not significantly associated with disease type, but were significantly associated with disease severity.

conclusionsH. pylori infection was associated with chronic gastritis type (endoscopic classification) and disease severity. Abnormal EGF and PGE2 levels may be associated with H. pylori-positive LGIN in Han Chinese patients in central China.
