Creatinine clearance and inappropriate dose of rivaroxaban in Japanese patients with non-valvular atrial fibrillation.

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
In Japanese surveillance in an early phase after the approval of rivaroxaban, inappropriate underdose was frequently utilized. The aim of this study was to describe the prevalence and predictors of the inappropriate usage of rivaroxaban in a single-center, cardiovascular-specialized hospital. Consecutive 661 non-valvular atrial fibrillation (NVAF) patients treated with rivaroxaban between 2012 and 2017 were recruited. After excluding 30 patients without assessment of creatinine clearance (CCr), the proportion and predictors of inappropriate underdose were analyzed. Additionally, patient outcomes, including thromboembolism (ischemic stroke or systemic embolism) and major bleeding, were determined. In patients with CCr ≥ 50 mL/min (n = 532) and < 50 mL/min (n = 98), inappropriate underdose and overdose were used in 123 (23%) and 8 (8%), respectively. The predictors of inappropriate underdose (in patients with CCr ≥ 50 mL/min) were CCr [50-63 mL/min (the lowest tertile) compared to ≥ 64 mL/min], age ( ≥ 75 years), female gender, prescription of antiplatelet, and coexistence of heart failure. Although PT under rivaroxaban was lower in patients with inappropriate underdose than in those with an appropriate dose, no significant increase in the incidence of thromboembolism or major bleeding was observed within the mean follow-up of 683 days. Inappropriate underdose of rivaroxaban was frequently observed for NVAF patents even in a cardiovascular hospital, particularly in patients with CCr adjacent to the dose reduction criteria. The responses of PT and the incidence of adverse outcomes under an inappropriate dose of rivaroxaban should be further investigated.
