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
objectiveThe Maryland Medicaid health home program, established through the Affordable Care Act's Medicaid health home waiver, integrates primary care services into specialty mental health programs for adults with serious mental illness (SMI). We evaluated the effect of this program on all-cause, physical, and behavioral health emergency department (ED) and inpatient utilization.
methodUsing marginal structural modeling to control for time-invariant and time-varying confounding, we analyzed Medicaid administrative claims data for 12,232 enrollees with SMI from October 1, 2012 to December 31, 2016; 3319 individuals were enrolled in a BHH and 8913 were never enrolled.
resultsHealth home enrollment was associated with reduced probability of all-cause (PP: 0.23 BHH enrollment vs. 0.26 non-enrollment, p < 0.01) and physical health ED visits (PP: 0.21 BHH enrollment vs. 0.24 non-enrollment, p < 0.01) and no effect on inpatient admissions per person-three-month period.
conclusionThese results suggest the Maryland Medicaid health home waiver's focus on supporting physical health care coordination by specialty mental health programs may be preventing ED visits among adults with SMI, although effect sizes are small.
