Predictors and Outcomes of Inappropriate Dosing of Direct Oral Anticoagulants in Patients Receiving Transcatheter Aortic Valve Implantation.
Article in Cardiology and therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03192774 (A Prospective Follow-up Assessment of Transcatheter Aortic Valve Implantation in Bad Segeberg), which is not on this 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.

Abstract
introductionDirect oral anticoagulant (DOAC) dose adjustment is based on age, renal function, and body weight. There is a paucity of data describing the factors associated with the prescription of inappropriate dosage and their impact on clinical outcomes among patients receiving transcatheter aortic valve implantation (TAVI).
methodsIn a single-center study, 432 patients who were on long-term DOAC therapy and underwent TAVI between 2015 and 2022 were included. We analyzed the predictors and outcomes of inappropriate dosing of DOACs; namely apixaban, dabigatran, edoxaban, and rivaroxaban. A composite endpoint, including all-cause mortality, life-threatening/major bleeding, stroke, peripheral thromboembolic complications, or myocardial infarction, was assessed after 1 year.
resultsIn this TAVI cohort, inappropriate DOAC dosing was observed in 20.6% of patients. Inappropriate DOAC dosage was related to female gender (adj. odds ratio [OR] 2.72, 95% confidence interval [CI] 1.64-4.51, p < 0.001) as well as lower estimated glomerular filtration rate (eGFR) (adj. OR 0.99, 95% CI 0.98-1.00, p = 0.019), and to the administration of non-rivaroxaban DOACs (adj. OR 0.28, 95% CI 0.16-0.50, p < 0.001). After 1 year, patients on both appropriate and inappropriate DOAC dosage exhibited comparable rates of the composite endpoint (OR 0.88, 95% CI 0.53-1.46, p = 0.622). Old age (adj. OR 1.05, 95% CI 1.01-1.10, p = 0.018) as well as anemia (adj. OR 0.86, 95% CI 0.75-0.99, p = 0.031) emerged as independent predictors of the composite endpoint.
conclusionsIn this TAVI cohort, female gender and renal insufficiency were associated with inappropriate DOAC dosage, whereas rivaroxaban was linked to appropriate dosing. Inadequate DOAC dosage did not translate into a worse outcome in our TAVI population.
