Adjusted ORs are measurements of being at risk of needing a lower dose of acenocoumarol when carrying an allelic variant or when being 1 year older. Patient sex and use of other drugs were finally excluded from the multivariate model because they did not show significant effects (P = .41 and P = .56, respectively) or play a role in any interactions.
CI indicates confidence interval.
On Wald testing.
