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

objectiveTo investigate the association between recovery support services (peer and community support services) and Medicaid claims. STUDY SETTING AND

designThis is an observational study. We estimated multivariate models with Medicaid billing charges and Medicaid reimbursements as the primary outcome and the yearly number of peer and community support encounters as the variables of interest. DATA SOURCES AND ANALYTICAL SAMPLES: We obtained New Mexico Medicaid claims data for 3094 individuals aged 18 years and older who received recovery support services for substance use disorder (SUD) treatment between 2018 and 2021. PRINCIPAL

findingsAn additional community support worker encounter was associated with decreases of $278.42 (p < 0.01) in annual Medicaid billing charges and $89.69 (p < 0.01) in annual reimbursements. Results are robust across different types of substance use disorders, different types of charges, and a variety of functional forms. We found less consistent evidence for the association between peer support workers and Medicaid claims. Point estimates were statistically significant for the association between encounters with peer support workers and billing charges ($119.01; p < 0.05), but not for reimbursements. Larger and more precisely estimated effects were found for the association between encounters with peer support workers and Medicaid claims for individuals with alcohol use disorder and for inpatient services.

conclusionThese results suggest that increased engagement with community support workers for substance use disorder is associated with reductions in Medicaid billing charges and reimbursements for other services.
