Massachusetts health care reform and reduced racial disparities in minimally invasive surgery.
Article in JAMA surgery, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 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
importanceRacial disparities in receipt of minimally invasive surgery (MIS) persist in the United States and have been shown to also be associated with a number of driving factors, including insurance status. However, little is known as to how expanding insurance coverage across a population influences disparities in surgical care.
objectiveTo evaluate the impact of Massachusetts health care reform on racial disparities in MIS. DESIGN, SETTING, AND
participantsA retrospective cohort study assessed the probability of undergoing MIS vs an open operation for nonwhite patients in Massachusetts compared with 6 control states. All discharges (n = 167,560) of nonelderly white, black, or Latino patients with government insurance (Medicaid or Commonwealth Care insurance) or no insurance who underwent a procedure for acute appendicitis or acute cholecystitis at inpatient hospitals between January 1, 2001, and December 31, 2009, were assessed. Data are from the Hospital Cost and Utilization Project State Inpatient Databases.
interventionThe 2006 Massachusetts health care reform, which expanded insurance coverage for government-subsidized, self-pay, and uninsured individuals in Massachusetts. MAIN OUTCOMES AND MEASURES: Adjusted probability of undergoing MIS and difference-in-difference estimates.
resultsPrior to the 2006 reform, Massachusetts nonwhite patients had a 5.21-percentage point lower probability of MIS relative to white patients (P < .001). Nonwhite patients in control states had a 1.39-percentage point lower probability of MIS (P = .007). After reform, nonwhite patients in Massachusetts had a 3.71-percentage point increase in the probability of MIS relative to concurrent trends in control states (P = .01). After 2006, measured racial disparities in MIS resolved in Massachusetts, with nonwhite patients having equal probability of MIS relative to white patients (0.06 percentage point greater; P = .96). However, nonwhite patients in control states without health care reform have a persistently lower probability of MIS relative to white patients (3.19 percentage points lower; P < .001). CONCLUSIONS AND RELEVANCE: The 2006 Massachusetts insurance expansion was associated with an increased probability of nonwhite patients undergoing MIS and resolution of measured racial disparities in MIS.
