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
introductionThe Affordable Care Act increased insurance coverage for patients residing in states that expanded Medicaid coverage, but its impact on the outcomes of intrahepatic cholangiocarcinoma (ICC) is not clear. Therefore, we examine the impact of Medicaid expansion (ME) on access to treatment and outcomes of ICC.
methodsWe queried the National Cancer Database (NCDB) data for patients with a diagnosis of ICC (2010-2018). Difference-in-difference (DID) analysis was performed to assess the impact of January 2014 ME on curative-intent surgical resection, multimodal therapy, neoadjuvant chemotherapy, 30-day mortality, and overall survival (OS).
resultsOf the 2150 patients included in the study,1574 (73.2%) and 576 (26.8%) patients lived in non-ME and ME states, respectively. On adjusted DID, ME was independently associated with receipt of curative-intent surgical resection (DID coefficient: 0.05, 95% confidence interval [95% CI]: 0.04-0.06, p = 0.002) and multimodal therapy (DID coefficient: 0.08, 95% CI: 0.06-0.10, p = 0.004). In addition, ME was associated with improved OS in ME states (hazard ratio [HR]: 0.73, 95% CI: 0.62-0.87, p = 0.001) but not in non-ME states (HR: 0.95, 95% CI: 0.80-1.12, p = 0.536).
conclusionME status consistently predicted increased utilization of care processes that improved ICC outcomes, including greater rates of curative-intent surgery and multimodal therapy.
