Spillover Effects From A Consumer-Based Intervention To Increase High-Value Preventive Care.
Article in Health affairs (Project Hope), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
Increasing the use of high-value medical services and reducing the use of services with little or no clinical value are key goals for efficient health systems. Yet encouraging the use of high-value services may unintentionally affect the use of low-value services. We examined the likelihood of high- and low-value service use in the first two years after an insurance benefit change in 2011 for one state's employees that promoted use of high-value preventive services. In the intervention group, compared to a control sample with stable benefit plans, in year 1 the likelihood of high-value service use increased 11.0 percentage points, and the likelihood of low-value service use increased 7.9 percentage points. For that year we associated 74 percent of the increase in high-value services and 57 percent of the increase in low-value services with greater use of preventive visits. Our results imply that interventions aimed at increasing receipt of high-value preventive services can cause spillovers to low-value services and should include deterrents to low-value care as implemented in later years of this program.
