Did copayment changes reduce health service utilization among CHIP enrollees? Evidence from Alabama.
Article in Health services research, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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 explore whether health care utilization changed among enrollees in Alabama's CHIP program, ALL Kids, following copayment increases at the beginning of fiscal year 2004. DATA SOURCES: Data on all ALL Kids enrollees over 1999-2009 are obtained from claims files and the state's administrative database. STUDY
designWe use pooled month-level data for all enrollees and conduct covariate-adjusted segmented regression models. Health services considered are inpatient care, emergency department (ED) visits, brand-name prescription drugs, generic prescription drugs, physician office visits and outpatient-services, ambulance services, allergy treatments, and non-preventive dental services. Physician well-visits, preventive dental services, and service use by Native-Americans--which saw no copayment increases--serve as counterfactuals. PRINCIPAL
findingsThere are significant declines in utilization for inpatient care, physician visits, brand-name medications, and ED visits following the copayment increases. By and large, utilization did not decline, or declined only temporarily, for those services and for those enrollees that who not subject to increased copayments.
conclusionsCopayment increases reduced utilization of many health services among ALL Kids enrollees. Concerns remain regarding the long-term health consequences to low-income children of copayment-induced reductions in health care utilization.
