Medicaid expansion and surgery for HPB/GI cancers: NCDB difference-in-difference analysis.
Article in American journal of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
backgroundIt is unclear if Medicaid expansion improved access to surgical resection for hepatopancreatobiliary (HPB) and gastrointestinal (GI) cancers.
methodsThis was a quasi-experimental, cohort study using difference-in-difference analysis to evaluate differences in surgical resection for HPB/GI cancers in the post-Medicaid expansion era compared to the pre-Medicaid expansion era among patients residing in states that had Medicaid expansion versus not.
resultsDuring the pre- (2011-2013) and post-Medicaid expansion (2015-2017) eras, there were 49,954 patients between the ages of 40-64 who had liver cancer (n = 19,384; 38.8%), pancreatic cancer (n = 14,351; 28.7%), colorectal liver metastasis (n = 7566; 15.1%), or gastric cancer (n = 8653; 17.3%). 43.2% resided in expansion states (n = 21,577). There were no significant differences in the overall rates of surgical resection between expansion and non-expansion states before and after Medicaid expansion.
conclusionsMedicaid expansion did not impact surgical resection for HPB/GI cancers.
