Use of hormone replacement therapy and risk of venous thromboembolism: nested case-control studies using the QResearch and CPRD databases

The study provides more information for clinicians and women about relative VTE risks and highlights that transdermal HRT is the preferred choice over other forms of treatment with no associated VTE risks.
