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.

2 · The registry

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

purposeEffective intraprocedural anticoagulation is considered essential to minimize the risk of thromboembolism in catheter ablation (CA) of atrial fibrillation (AF). The effect of interrupted apixaban on intraprocedural heparin dosing requirements and levels of achieved anticoagulation with heparin has not been well studied. The purpose of the present study was to compare heparin administration and activated clotted times (ACTs) for patients undergoing CA for AF treated with interrupted apixaban before the procedure with patients on uninterrupted warfarin.

methodsConsecutive patients undergoing CA for AF treated with interrupted apixaban or uninterrupted warfarin were prospectively enrolled. Heparin administration determined by a standard protocol and normalized to patient weight and procedure duration, as well as rapidity, and degree of anticoagulation with heparin (as measured by mean ACT, peak ACT, time to ACT ≥300 s, and time to ACT ≥350 s) were compared between the groups.

resultsForty-eight patients were enrolled (25 apixaban and 23 warfarin). Heparin administered by bolus (51.3 ± 21.5 vs 27.8 ± 9.6 units/kg/h; p < 0.001) and mean heparin drip rate (25.3 ± 3.6 vs 20.7 ± 2.4 units/kg/h; p < 0.001) were significantly higher in the apixaban group compared to the warfarin group. Despite greater heparin administration, apixaban patients achieved a significantly lower mean ACT (332.3 ± 17.0 vs 384.5 ± 53.9; p < 0.001) and peak ACT (369.5 ± 22.6 vs 432.3 ± 75.8, p < 0.001) compared to the warfarin group. The time to ACT ≥350 s (66.7 ± 35.8 vs 26.9 ± 34.0; p < 0.001) was significantly longer for apixaban-treated patients. Outcome differences persisted after analysis using linear models and Cox proportional hazard regression with adjustment for propensity scores.

conclusionsA standard intraprocedural heparin protocol results in delayed and lower levels of anticoagulation as measured by the ACT for interrupted apixaban-treated patients in comparison to those on uninterrupted warfarin during CA of AF.
