Cardiac Imaging Trends from 2010 to 2019 in the Medicare Population.
Article in Radiology. Cardiothoracic imaging, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 49 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
purposeTo evaluate changes in utilization of cardiac imaging-transthoracic, transesophageal, and stress echocardiography (TTE, TEE, and SE), coronary CT angiography (cCTA), cardiac MRI (cMRI), myocardial perfusion imaging (MPI), and cardiac positron emission tomography (cPET). MATERIALS AND
methodsThe 2010-2019 Physician/Supplier Procedure Summary files were used to find imaging utilization per 100 000 Medicare beneficiaries. Global and professional claims were aggregated, representing total interpretive services. Specialty codes identified provider specialty. Results were stratified by physician offices, hospital outpatient departments (HOPDs), inpatient setting, and the emergency department.
resultsFrom 2010 to 2019, there was a partial shift from cardiologist offices to the HOPD for TTE (office: -23%; HOPD: +107%) and SE (office: -44%; HOPD: +11%). Cardiologist cCTA also shifted from the office (-57%) to the HOPD (+211%). Radiologist-performed cCTA grew in all locations but most in the HOPD (+355%), with radiologists performing more cCTA than cardiologists in all settings. cMRI rates remain low but rose in the HOPD for both cardiologists (+209%) and radiologists (+207%). Cardiologist MPI rates dropped dramatically in the office (-52%), with a smaller absolute rate increase in the HOPD (+71%). cPET nearly tripled in the cardiology office (+193%), but rates remained steady for radiologists.
conclusionWhile most cardiologist in-office imaging has shifted to the HOPD, there has been an increase in in-office cPET, likely due to a combination of technological advances, interpretation familiarity, and financial incentives. Radiologist cCTA rates continue to increase, representing a growing opportunity for radiologists to collaborate in cardiac imaging.
