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
backgroundGastric cancer is one of the most common cancers with high mortality. In Iran, the high-risk regions include Northern and Northwestern parts. The aim of this study was to assess the operative link on gastritis assessment- and operative link on gastric intestinal metaplasia-based staging in patients with upper gastrointestinal symptoms.
methodsTotally, 345 patients underwent upper gastrointestinal endoscopy. Also, the status of Helicobacter pylori infection was evaluated using rapid urease test and histological method. Moreover, histological changes were assessed using the Update Sydney System. The operative link on gastritis assessment- and operative link on gastric intestinal metaplasia-based stages of 0-II were considered as low-risk stages and stages III and IV were considered as high-risk stages.
resultsMost of the patients were lower than 60 years (245 patients, 71%), and 71.9% of our patients had H. pylori infection. The frequency of atrophic gastritis and intestinal metaplasia was 44.9% and 25.2%, respectively (P < .001). Eleven patients (73.7%) with gastric adenocarcinoma had a low risk and 2 patients with low-grade dysplasia had a high risk of operative link on gastritis assessment and operative link on gastric intestinal metaplasia. Almost, 62.5% of gastric cancer patients with an intestinal type of gastric adenocarcinoma were at low-risk stages.
conclusionsAlthough high stages of operative link on gastritis assessment and operative link on gastric intestinal metaplasia need further follow-up, lower stages of atrophy or intestinal metaplasia also require follow-up. Furthermore, operative link on gastritis assessment method in detecting a greater number of patients who need follow-up is more successful and profitable.
