Ethnic disparities in gastric cancer incidence and survival in the USA: an updated analysis of 1992-2009 SEER data.
Article in Digestive diseases and sciences, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 50 papers, 1 of them a synthesis that pooled it.
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 (GC) is the second-leading cause of cancer-related deaths worldwide, with overall 5-year survival less than 20%. However, limited data exist investigating ethnic disparities in stage-specific GC incidence and survival in the USA.
aimTo evaluate ethnicity-specific differences in GC incidence and survival in the USA.
methodsUsing data from the surveillance, epidemiology, and end results 1992-2009 population-based cancer registry, we evaluated ethnic disparities in GC incidence stratified by year of diagnosis, cancer stage at presentation, and geographical distribution of disease. Ethnic disparities in survival were evaluated using Kaplan-Meier and multivariate Cox proportional hazards models.
resultsAmong men and women combined and among all cancer stages, Asians had the highest incidence of GC, more than double that among Whites (15.6 vs. 7.4 per 100,000/year, p < 0.005). In addition, Asians had the highest survival of all race groups (3-year survival: 26.6%, p < 0.001). Compared with Whites, Blacks (12.8 vs. 7.4 per 100,000/year, p < 0.005) and Hispanics (12.9 vs. 7.4 per 100,000/year, p < 0.005) also had significantly higher incidence of GC. Multivariate Cox models (adjusted for age, year of diagnosis, sex, race/ethnicity, stage of disease, and treatment received) demonstrated significantly higher survival in Asians compared with Whites (HR 0.82, 95% CI 0.80-0.85, p < 0.04).
conclusionsRacial/ethnic disparities in GC incidence and survival exist in the USA Asians have the highest incidence of GC and the highest overall survival. Outlining high-risk groups may inform potential screening practices and physician awareness for GC.
