#' 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.
