Impact of Medicaid Expansion on Stage at Diagnosis for US Adults with Pancreatic Cancer: a Population-Based Study.
Article in Journal of racial and ethnic health disparities, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
introductionWe evaluated whether Medicaid expansion is associated with earlier stage at diagnosis for pancreatic cancer taking into account key demographic, clinical, and geographic factors.
methodsWe obtained Surveillance, Epidemiology, and End-Results (SEER-18) data on individuals diagnosed with pancreatic cancer from 2007 to 2016 (< 65 years of age). We defined non-metastatic as either local or regional disease (vs. metastatic disease). To estimate the association of Medicaid expansion with pancreatic cancer stage at diagnosis, we used a difference-in-differences model, at the individual level, comparing those from early-adopting states in 2014 to non-early-adopting states. We utilized cluster-robust standard errors and explored the role of demographic factors (race, sex, insurance at diagnosis), clinical indicator (disease in the head of the pancreas), and county characteristics (Urban Influence Code, Social Deprivation Index).
resultsIn the univariable setting, the probability of non-metastatic disease at diagnosis increased by 3.9 percentage points (ppt) for those from Medicaid expansion states post-expansion (n = 36,609). After adjustment for covariates, the ppt was attenuated to 2.7. Of particular note, we observed evidence of interactions with sex and race. The beneficial effect was less pronounced for men (increase in the probability of non-metastatic stage at diagnosis by 2.1ppt) than women (3.6ppt) and non-existent for blacks (- 3.1ppt) compared to whites (4.9ppt) and other races (4.8ppt).
conclusionMedicaid expansion is associated with increased probability of non-metastatic stage at diagnosis for pancreatic cancer; however, this beneficial effect is not uniform across sex and race. This underscores the need to investigate the impact of policy and implementation strategies on pancreatic cancer survival disparities.
