About this trial
The NoCVT study will investigate CVT (2014-2023) in a large Norwegian population (\> 3 millions) using several approaches combining existing health registries, clinical databases and new prospectively collected clinical data to explore epidemiology, risk factors, diagnostics, treatment, and the long-term prognosis of CVT.

Trial population
A retrospective hospital-based chart review will be conducted at 13 different hospitals covering approximately 3 million inhabitants in Norway. More precis, a validated ICD-10 search will be made in the clinical database for patients with the diagnosis of CVT in the period between January 1, 2014, and December 31, 2023. Data from the clinical databases at these hospitals will be linked with the mandatory National Health Registries for baseline data and prospectively collected follow-up data. The National Health Registries involved are Statistics Norway (SSB), Norwegian Prescription Database (NorPD), Norwegian Patient Registry (NPR) and Cause of Death Registry (DÅR). In addition a clinical follow-up interview will be conducted with emphasis on long-term outcomes.
