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 prevalence of chronic conditions continues to increase in the United States, disproportionately affecting low-income women and Medicaid beneficiaries. This study examined whether an accountable care approach implemented in Oregon Medicaid, known as Coordinated Care Organizations (CCOs), which integrates the delivery of physical and mental health services, may improve high-value healthcare utilization during pregnancy among female Oregon Medicaid beneficiaries with chronic mental-physical comorbidities (MPCs).
methodsWe performed a retrospective analysis of Oregon Medicaid data from 2008 to 2016, linked with birth certificates and hospital discharge records. Measures of high-value utilization included timely and adequate prenatal care visits, preventable hospitalizations, and preventable emergency department (ED) visits. We utilized a quasi-experimental difference-in-differences approach, comparing the pre-post changes in the outcomes between CCO enrollees and other Medicaid beneficiaries.
resultsCCO enrollment was associated with greater odds of having the first prenatal care visit in the first trimester of pregnancy (OR 1.51, CI 1.21, 1.88) and the adequacy of prenatal care (OR 1.40, CI 1.10, 1.78) among women with MPCs. However, no statistically discernible associations were found for preventable hospitalization and ED visits. DISCUSSION: CCOs are effective in improving timely and adequate utilization of prenatal care among women with MPCs. Further research is needed to understand whether and how CCOs may reduce preventable costly healthcare utilization among women with MPCs during and beyond pregnancy.
