Utilization of triple antithrombotic therapy in patients with atrial fibrillation undergoing percutaneous coronary intervention.

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
backgroundTriple antithrombotic therapy (TAT), a combination of an oral anticoagulant and dual antiplatelet therapy (DAPT), is a key treatment for prevention of ischemic events in patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI). However, TAT is not extensively used because of the risk of bleeding. This study aimed to determine the utilization and influencing factors of TAT using real-world data in the non-vitamin K antagonist oral anticoagulants (NOACs) era.
methodsWe analyzed National Inpatient Sample data compiled by the Health Insurance Review & Assessment Service (HIRA-NIS) from 2011 to 2020. Patients with AF who underwent PCI with stent implantation and with an increased stroke risk were selected as candidates for TAT therapy. Demographic and clinical factors associated with TAT use were investigated using the chi-squared test and the Student t-test, and influencing factors were identified using multiple logistic regression.
resultsThe TAT utilization rate steadily increased from 30.3% in 2011 to 65.4% in 2020 (Cochran-Armitage trend test: p < 0.001) with an average of 45.9%. Positive influencing factors for TAT use were identified as congestive heart failure, history of previous stroke/transient ischemic attack/thromboembolism, valvular heart disease, and year. Negative influencing factors included insurance type (medical aid or Patriots & Veterans Insurance), type of medical institution (general hospitals or primary medical institutions), and comorbidities such as renal disease, liver disease, and history of the previous hemorrhage.
conclusionsThe utilization of TAT following PCI among high-stroke risk AF patients steadily increased from 2011 to 2020, reaching 65.4% by the end of the study period. However, in 2020, a significant proportion of 29.4% of patients still received DAPT, indicating that many AF patients undergoing PCI did not receive adequate antithrombotic therapy.
