Gastric Mucosal Status and Risk of Gastric Cancer in High-Risk Individuals: A Population-Based, Multicenter Prospective Study in China.

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
objectiveThis study explored the distributions of gastric mucosal status and their links to gastric cancer within urban high-risk individuals in China.
methodsFrom 2014 to 2015, a questionnaire survey was administered among individuals aged 40 to 69 years, residing for over 3 years in seven selected cities across China. Utilizing the questionnaire data, high-risk individuals for gastric cancer were screened. These identified high-risk individuals were invited to undergo endoscopy, followed by pathological examinations conducted for those with suspicious lesions. Prior cancer patients and those newly diagnosed with gastric cancer were excluded, and the remaining endoscopic participants were prospectively followed up until December 2021.
resultsThe prospective study followed 8911 individuals at high risk of gastric cancer for a median duration of 6.77 years. The incidence density of gastric cancer was 58.55 per 100,000 person-years. At baseline, the distributions of subjects across normal gastric mucosa, gastritis/ulcer/polyp, atrophic gastritis/intestinal metaplasia, and intraepithelial neoplasia groups were 47.09%, 36.27%, 9.57%, and 7.07%, respectively. Compared with normal gastric mucosa, the hazard ratios (HRs) for gastric cancer in the other groups were 0.89 [95% confidence interval (95%CI): 0.38-2.08], 1.52 (95%CI: 0.50-4.66), and 4.63 (95%CI: 1.98-10.82). When using the 40-54 age group as the reference, the HR for 55-69 age group was 3.49 (95%CI: 1.52-7.98).
conclusionAmong high-risk individuals with gastric cancer, the proportions of individuals exhibiting different gastric mucosal status inversely correlated with the severity of mucosal lesions, whereas the risk of gastric cancer progressively escalated with the increasing severity of mucosal lesions and advancing age.
