Expanding Prenatal Care to Unauthorized Immigrant Women and the Effects on Infant Health.

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
objectiveTo measure the effect of access to prenatal care on unauthorized and low-income, new legal permanent resident immigrant women and their offspring.
methodsWe used a difference-in-differences design that leverages the staggered rollout of Emergency Medicaid Plus by county from 2008 to 2013 as a natural experiment to estimate the effect on health service utilization for women and health outcomes for their infants. Regular Medicaid pregnancies were used as an additional control in a triple difference design.
resultsOur sample included pregnancies covered by Emergency Medicaid (35,182), Emergency Medicaid Plus (12,510), and Medicaid (166,054). After expansion of access to prenatal care, there was an increase in prenatal visits (7.2 more visits, 95% CI 6.45-7.96), receipt of adequate prenatal care (28% increased rate, CI 26-31), rates of diabetes screening (61% increased rate, CI 56-66), and fetal ultrasonograms (74% increased rate, CI 72-76). Maternal access to prenatal care was also associated with an increased number of well child visits (0.24 more visits, CI 0.07-0.41), increased rates of recommended screenings and vaccines (0.04 increased probability, CI 0.002-0.074), and reduced infant mortality (-1.01/1,000, CI -1.42 to -0.60) and rates of extremely low birth weight (less than 1,000 g) (-1.33/1,000, CI -2.44 to -0.21).
conclusionOur results provide evidence of increased utilization and improved health outcomes for unauthorized immigrants and their children who are U.S. citizens after introduction of prenatal care expansion in Oregon. This study contributes to the debate around reauthorization of the Children's Health Insurance Program in 2017.
