Risk factors of gallbladder cancer in Nepal: A case control study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundGallbladder cancer (GBC) is a rare, highly fatal disease with diagnosis in advanced stage and low survival rate. Nepal ranked 4th position with highest rates of GBC for 10 countries in 2020.
objectiveTo find the association between socio-demographic, behavioral and environmental factors associated with the development of GBC.
methodA case-control study was conducted in 2021/22 with newly diagnosed gallbladder cancer cases from three cancer-specialized hospitals and one tertiary (superspeciality) hospital. Controls were selected from the same tertiary hospital and one additional hospital providing services to gallbladder pathologies for a huge population, making a total of five hospitals involved in the study. The ratio of cases to control was 1:1. The data collection was done through telephonic interviews using structured questionnaires. The risk factors for GBC were assessed by using unconditional logistic regression to find odds ratios and 95% confidence level for bivariate and multivariate analysis. The statistical analysis was carried out in STATA 18.
resultA total of 240 respondents were enrolled in the study, among them half were GBC patients (cases) and half were gallbladder patients (controls). The average age of the respondents was 54.82±12.3 years, with female preponderance among both groups. On multivariate analysis, the risk factors studied were; parity ≥3 (AOR = 2.80, 95% CI: 1.17-6.66, P value 0.020), being ethnic group of Terai/Madhesi (AOR = 7.88, 95% CI: 3.16-19.66, P value <0.001), being Janajati (AOR = 3.36, 95% CI: 1.17-6.61, P value <0.001), having gallbladder related disease (AOR = 2.00, 95% CI:1.00-4.02, P value 0.049), consuming alcohol ≥100ml/day (AOR = 3.44, 95% CI:1.11-10.63, P value 0.032), exposed with pesticides ≥2 times in a year (AOR = 4.04, 95% CI: 1.27-12.89, P value 0.018) and consuming less vegetables and fruits (<1 times per day in a week) (AOR = 2.69, 95% CI:1.34-5.40, P value 0.005).
conclusionThe study reveals key GBC risk factors, offering vital insights for targeted screening, resource allocation, and public health measures to mitigate risks in Nepal.
