Patient- and system-level factors associated with racial/ethnic disparities in the delivery of guideline-concordant therapy among US patients with gastric cancer.
Article in Journal of surgical oncology, 2024. 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
backgroundDisparities in gastric cancer (GC) outcomes show a higher disease burden among minorities. We aimed to evaluate the associations between sociodemographic and system-level factors and guideline-concordant treatment among GC patients.
methodsCohort study with GC patients in the National Cancer Data Base (2006-2018) treated with upfront resection or neoadjuvant therapy (NAT). We used logistic regression to identify associations between deviations from guideline-concordant therapy and patient- and system-level factors, and Cox regression models to assess risk of death.
resultsThe cohort included 43 597 GC patients treated with endoscopic resection (8.9%), surgery only (47.1%), surgery and adjuvant therapy (20.6%), or NAT followed by surgery (23.5%). A total of 31 470 patients (72.2%) received guideline-concordant therapy. Relative to Non-Hispanic Whites (NHWs), Non-Hispanic Blacks (NHBs) (odds ratio [OR] 1.19, [95% confidence intervals 1.10-1.28]) and Asian/Pacific Islanders (APIs) (OR 1.12 [1.03-1.23]) had an increased risk of deviations from treatment guidelines. Medicare/Medicaid increased the risk of deviations while treatment at high-volume facilities decreased its risk for all races/ethnicities. Deviations from guidelines were associated with an increased risk of death (hazard ratio 1.56 [1.50-1.63].
conclusionsRacial disparities in the delivery of guideline-concordant therapy among GC patients are affected by several sociodemographic factors at the patient- and system-level.
