Vitamin K antagonists for prevention of stroke in non-valvular atrial fibrillation

Description

A pairwise subset extracted from a network meta-analysis of antithrombotic treatments for prevention of stroke in patients with non-valvular atrial fibrillation. The dataset includes direct comparisons of vitamin K antagonists versus placebo or control, with study-specific log odds ratios and standard errors for the stroke outcome.
