Racial and Ethnic Differences in Gastric Cancer by Stage of Diagnosis in the United States (2009-2019).

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
backgroundDespite the United States having a low overall gastric cancer incidence rate, there remain disparities by race/ethnicity. We examined the incidence of gastric cancer by stage at diagnosis among Hispanic, Asian/Pacific Islander (A/PI), American Indian/Alaska Native (AI/AN), and non-Hispanic Black (NHB) populations, compared with the non-Hispanic White (NHW) population, during 2009 to 2019.
methodsUsing Surveillance, Epidemiology, and End Results data, age-adjusted gastric cancer incidence rates, rate ratios (RR), and 95% confidence intervals (CI) were calculated by stage and race/ethnicity. Stratified analyses were performed by sex, age, and anatomic site.
resultsCompared with NHW individuals, the incidence rates of regional and distant-stage gastric cancer diagnoses were nearly two times higher in Hispanic (RRregional, 1.87; 95% CI, 1.78-1.97; RRdistant, 1.92; 95% CI, 1.84-2), A/PI (RRregional, 2.17; 95% CI, 2.04-2.30; RRdistant, 1.58; 95% CI, 1.49-1.68), and NHB (RRregional, 1.78; 95% CI, 1.67-1.88; RRdistant, 1.80; 95% CI, 1.71-1.89) individuals. In stratified analyses, the increased rate of advanced-stage diagnosis for Hispanic, A/PI, and NHB individuals remained generally consistent by sex and age, although young AI/AN individuals also had a significantly higher rate of distant gastric cancer (RR, 2.38; 95% CI, 1.36-3.83). By site, the increased rates of advanced-stage diagnosis were limited to noncardia and overlapping/unspecified gastric cancer, whereas these populations had lower rates of cardia gastric cancer than NHW individuals.
conclusionsHispanic, A/PI, and NHB individuals have disproportionately high advanced-stage noncardia gastric cancer rates compared with NHW individuals. IMPACT: This study has identified significant disparities in advanced-stage noncardia gastric cancer, suggesting the need to identify strategies to improve early detection in these populations.
