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

BACKGROUND Several factors determine the efficacy of warfarin anticoagulation in patients with non-valvular atrial fibrillation (NVAF). This study aimed to use data from the Chinese Atrial Fibrillation Registry study to assess the control of anticoagulation therapy in Chinese patients with NVAF treated with warfarin. MATERIAL AND METHODS From the Chinese Atrial Fibrillation Registry study the anticoagulant use and dosing, the time in therapeutic range (TTR) of the international normalized ratio (INR), and standard deviation of the observed INR values (SDINR), and their influencing factors were evaluated. RESULTS The median INR and SDINR were 2.04 (IQR 1.71-2.41) and 0.50 (IQR, 0.35-0.69), respectively. The median TTR was 51.7% (IQR, 30.6-70.1%) and only 25.1% had a TTR ≥70%. Age was ≥70 years (OR, 0.72; 95% CI, 0.55-0.94; P=0.015), bleeding history (OR 0.48; 95% CI, 0.23-0.89; P=0.029), the use of a single drug (OR, 0.62; 95% CI, 0.42-0.92; P=0.016), more than drug (OR, 0.60; 95% CI, 0.41-0.88; P=0.009), and lack of assessment of bleeding risk (OR, 0.72; 95% CI, 0.54-0.97; P=0.033) were associated with TTR <70% (INR 2.0-3.0). Coronary heart disease (CHD) and peripheral artery disease (PAD) (OR, 0.69; 95% CI, 0.52-0.90; P=0.007) and diabetes mellitus (OR, 0.79; 95% CI, 0.62-0.99; P=0.044) were associated with increased variability in INR (SDINR ≥0.5). CONCLUSIONS In Chinese patients with NVAF, warfarin anticoagulation was associated with lower TTR and less stable anticoagulation than in current guidelines, and risk factors for reduced safety and efficacy were identified.
