Changes in Helicobacter pylori Status in Patients Who Underwent Partial Gastrectomy for Gastric Cancer Therapy.

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
The role of Helicobacter pylori eradication in patients with gastric cancer (GC) undergoing gastrectomy remains unknown because current evidence is limited. This retrospective study investigated H. pylori infection status, eradication therapy, and success rates based on surgical methods. A total of 2827 patients underwent gastrectomy for GC; 1510 (53.4%) tested positive for H. pylori, 1121 (39.7%) tested negative, and 196 (6.9%) were not tested. Among H. pylori-positive patients, 765 underwent eradication therapy, with treatment failure in 36 patients. Among the untreated patients, H. pylori was observed to have spontaneously disappeared by follow-up in 206 of 745 patients. The proportion of patients with spontaneous negative conversion was higher in the proximal and pylorus-preserving gastrectomy groups than in the distal gastrectomy group. However, no difference was observed in the failure rate of eradication therapy based on the surgical method used.
