Resource Use Following Revascularization for Multivessel Coronary Artery Disease.
Article in Journal of the American Heart Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundCoronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) are the 2 revascularization modalities for patients with severe coronary artery disease. While CABG has often demonstrated benefits over PCI in multivessel coronary artery disease, analyses of cost effectiveness have previously shown conflicting results and are limited by sample size, follow-up time, and lack of contemporary data.
methodsWe performed an analysis of resource use following elective, urgent, or emergent PCI or CABG from January 1, 2009, to December 31, 2018, with up to 14 years of follow-up. A provincial database was used to collect the associated data. The average cost for each event was calculated from Canadian Institute of Health Information data and was adjusted for inflation on the basis of the Bank of Canada consumer price index. Cost for each group was calculated for readmission to the hospital and repeat revascularization. Secondary outcomes included rates of death, myocardial infarction, rehospitalization, and repeat revascularization.
resultsOf 23 243 patients who underwent angiography, 7359 were included in this study. Overall costs and costs per patient were significantly higher following PCI compared with CABG. Patients who underwent PCI required $19 165 per person in inflation-adjusted health care resource costs compared with $12 612 for CABG. Furthermore, patients who underwent PCI had higher rates of death, myocardial infarction, rehospitalization, and repeat revascularization (
conclusionsPatients with multivessel coronary artery disease experience fewer adverse events and use fewer health care resources after discharge following CABG compared with PCI. Appropriate selection of CABG versus PCI may help reduce readmissions and health care costs following revascularization.
