Clinical characteristics of hospitalized patients with benign gallbladder disease: a large-scale retrospective analysis.
Article in BMC gastroenterology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundBenign gallbladder disease, including gallstones, gallbladder polyps, and gallbladder adenomyosis, is one of the most common disorders of the digestive system worldwide and poses a substantial clinical and economic burden. Despite its high prevalence, the clinical characteristics and risk profiles of hospitalized patients with benign gallbladder disease are not well defined, especially compared with population-based screening cohorts. This study aimed to analyze the clinical characteristics of hospitalized patients with benign gallbladder disease using a large dataset and to compare these findings with those reported in physical examination populations.
methodsA total of 36,298 patients admitted to the gallstone center of a tertiary hospital in Shanghai between 2019 and 2024 for benign gallbladder disease were included in the study. Basic patient information was collected from the electronic medical records system in accordance with the international classification of diseases. Descriptive statistics and Multinomial logistic regression methods were employed to analyze the clinical characteristics of patients and identify risk factors associated with gallbladder inflammatory conditions.
resultsThe mean age of patients with gallstones was 50.21 ± 15.31 years, 43.90 ± 13.53 years for gallbladder polyps, and 49.36 ± 13.28 years for gallbladder adenomyosis. The male-to-female ratio in the gallstone population was approximately 1:1.38 (13,175:18,304), gallbladder polyps was 1.03:1(male: female = 3198:3113) and gallbladder adenomyosis was 1:1.28(male: female = 1057:1351); the risk of gallbladder stones in menstruating women was 0.625 times that in postmenopausal women (95% CI: 0.575-0.680, p < 0.0001), and gallbladder polyps were 1.555 times(95% CI: 1.439-1.680, p < 0.0001). Multinomial logistic regression analysis demonstrated that age, male, gallstones, common bile duct stones(CBDS) and diabetes mellitus(DM) were significantly associated with the inflammatory state of the gallbladder(all p < 0.001).
conclusionsGallstones is the primary cause of hospitalisation for benign gallbladder disease, and the risk is higher in postmenopausal women. Middle age, male, gallstones, CBDS and DM are identified as risk factors for gallbladder inflammation. Although gallbladder polyps and adenomyosis showed patterns similar to those in general populations, findings from hospitalized cohorts may not fully represent broader, unscreened populations due to a higher prevalence of severe or symptomatic cases.
