1 · What the graph read from 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.

2 · The registry

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

Extensive undertreatment of substance use disorders has focused attention on whether the expansion of eligibility for Medicaid under the Affordable Care Act (ACA) has promoted increased coverage and treatment of these disorders. We assessed changes in coverage and substance use disorder treatment among low-income adults with the disorders following the 2014 ACA Medicaid expansion, using data for 2008-15 from the National Survey on Drug Use and Health. The percentage of low-income expansion state residents with substance use disorders who were uninsured decreased from 34.4 percent in 2012-13 to 20.4 percent in 2014-15, while the corresponding decrease among residents of nonexpansion states was from 45.2 percent to 38.6 percent. However, there was no corresponding increase in overall substance use disorder treatment in either expansion or nonexpansion states. The differential increase in insurance coverage suggests that Medicaid expansion contributed to insurance gains, but corresponding treatment gains were not observed. Increasing treatment may require the integration of substance use disorder treatment with other medical services and clinical interventions to motivate people to engage in treatment.
