What does Medicaid expansion mean for cancer screening and prevention? Results from a randomized trial on the impacts of acquiring Medicaid coverage.

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
backgroundThe Oregon Medicaid lottery provided a unique opportunity to assess the causal impacts of health insurance on cancer screening rates within the framework of a randomized controlled trial. Prior studies regarding the impacts of health insurance have almost always been limited to observational evidence, which cannot be used to make causal inferences.
methodsThe authors prospectively followed a representative panel of 16,204 individuals from the Oregon Medicaid lottery reservation list, collecting data before and after the Medicaid lottery drawings. The study panel was divided into 2 groups: a treatment group of individuals who were selected in the Medicaid lottery (6254 individuals) and a control group who were not (9950 individuals). The authors also created an elevated risk subpanel based on family cancer histories. One year after the lottery drawings, differences in cancer screening rates, preventive behaviors, and health status were compared between the study groups.
resultsMedicaid coverage resulted in significantly higher rates of several common cancer screenings, especially among women, as well as better primary care connections and self-reported health outcomes. There was little evidence found that acquiring Medicaid increased the adoption of preventive health behaviors that might reduce cancer risk.
conclusionsMedicaid coverage did not appear to directly impact lifestyle choices that might reduce cancer risk, but it did provide access to important care and screenings that could help to detect cancers earlier. These findings could have long-term population health implications for states considering or pursuing Medicaid expansion. Cancer 2016;122:791-797. © 2015 American Cancer Society.
