*Multivariate model 1: HAS-BLED Score dichotomised in two categories: low risk (score 0–2) and high risk (score ≥3) for intracerebral haemorrhage and for CHA₂DS₂-VASc Score dichotomised in two categories: medium risk (score 2–4) and high risk (≥5) for recurrent ischaemic stroke.

Multivariate model 2: age and history of hypertension.
