Oral anticoagulant therapy and outcome in patients with stroke. A retrospective nation-wide cohort study in Austria 2012-2017.

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
purposePatients with stroke are at high risk of recurrence of vascular events. Non-vitamin K oral anticoagulant (NOAC) and vitamin K antagonists (VKA) are used as secondary prophylaxis. The aim of this study was to evaluate the utilization of NOAC and VKA, and their impact on re-stroke or death in Austria.
methodsWe analyzed retrospective data between 2012 and 2017 from medical services covered by the health insurance funds, which provides health care for all residents in Austria. Patients without anticoagulant medication 3 months preceding the index event were eligible.
results76 354 patients were discharged with a hospital diagnosis of stroke. From these, 16 436 patients with a median age of 78 years received VKA or NOAC. After adjustment, the recurrence of stroke was less frequent in patients with NOAC compared to those with VKA (HR 0.87; 95%CI 0.77-0.97). However, there was no difference in mortality rate after adjustment for age, sex, and co-morbidities for patients with NOAC (HR 1.0; 95%CI 0.92-1.08). Diabetes (HR 1.25, 95%CI 1.08-1.45; HR 1.25, 95% CI 1.13-1.38) and cardiovascular disease (HR 1.43, 95%CI 1.24-1.65; HR 1.27, 95%CI 1.16-1.39) were significantly associated with re-stroke or death. Younger age (p = 0.0028; HR 0.99, 95%CI 0.99-0.99) was significantly associated with re-stroke, and advanced age (p < 0.0001; HR 1.09, 95%CI 1.08-1.09) with death.
conclusionNOAC prescription is related with a reduced risk of re-stroke but increased mortality compared to patients with VKA. The event risk is associated with diabetes, cardiovascular disease and age.
