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

backgroundVitamin K antagonists (VKA) have a narrow therapeutic range, and literature analysis reveals poor quality of anticoagulation control. We sought to assess the prevalence of poor anticoagulant control in patients under VKA treatment in the prevention of stroke for atrial fibrillation (AF). HYPOTHESIS: Control of anticoagulation with VKA is inadequate in a high percentage of patients with AF.

methodsPatients with AF under VKA treatment were prospectively recruited in this observational registry. The sample comprised 948 patients. The estimated time spent in the therapeutic range (TTR) was calculated, and variables related with a TTR >65% were analyzed.

resultsMean age was 73.8 ± 9.4 years, and 42.5% of the patients were women. Mean TTR was 63.77% ± 23.80% for the direct method and 60.27% ± 24.48% for the Rosendaal method. Prevalence of poor anticoagulation control was 54%. Variables associated with good anticoagulation control were university studies (odds ratio [OR]: 1.99, 95% confidence interval [CI]: 1.08-3.64), chronic hepatic disease (OR: 8.15, 95% CI: 1.57-42.24), low comorbidity expressed as Charlson index (OR: 0.87, 95% CI: 0.76-0.99), no previous cardiac disease (OR: 0.64, 95% CI: 0.41-0.98), lower risk of bleeding assessed as hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly age, and use of drugs or alcohol (HAS-BLED; OR: 0.81, 95% CI: 0.69-0.95), and lower heart rate (OR: 0.99, 95% CI: 0.98-0.99).

conclusionsPatients who receive VKA to prevent stroke for AF spend less than half the time within therapeutic range.
