1 · What the graph read from 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.

Abstract

The Perioperative Anticoagulation Use for Surgery Evaluation (PAUSE) study prospectively evaluated a prespecified periprocedural-interruption strategy of direct oral anticoagulants (DOACs) among patients with atrial fibrillation. Logistic regression analyses were performed to identify clinical parameters associated with residual DOAC levels ≥30 ng/mL or ≥50 ng/mL. Patients undergoing low-bleed-risk procedures were more likely to have residual levels of ≥30 ng/mL and ≥50 ng/mL. For low-risk procedures, age ≥75 years, female sex, a creatinine clearance (CrCl) <50 mL/min, and an interruption of <36 hours were associated with a greater likelihood of levels ≥30 ng/mL, whereas age ≥75 years, female sex, a CrCl of <50 mL/min, and standard DOAC dosing were associated with levels ≥50 ng/mL. For high-risk procedures, weight of <70 kg, CrCl <50 mL/min, and standard DOAC dosing were associated with residual levels ≥30 ng/mL, whereas female sex was associated with levels ≥50 ng/mL. For low-risk procedures, apixaban was associated with a higher likelihood of levels ≥30 ng/mL as compared with dabigatran (P = .0019) and of levels ≥50 ng/mL when compared with rivaroxaban (P = .0003). For high-risk procedures, apixaban was marginally associated with a higher likelihood of residual levels ≥30 ng/mL when compared with dabigatran (P = .05), whereas rivaroxaban was associated with a higher likelihood of levels ≥30 ng/mL as compared with apixaban. Further study is required to determine whether adjustments to perioperative plans based on these clinical parameters could result in a lower risk of residual DOAC levels. The PAUSE trial was registered at www.clinicaltrials.gov as #NCT2228798.
