Secondary study design	Case-control study
Study setting(s)	Hospital
Study type	Treatment
Scientific title	INcidence of VENous Thromboembolism after acute stroke in China
Study acronym	INVENT-China
Study objectives	1. Incidence of venous thromboembolism after acute stroke in China was lower than in western countries 2. Risk factors are different between Venous Thromboembolism (VTE) and non-VTE 3. Anticoagulation and neurological rehabilation can reduce the incidence
Ethics approval(s)	Approval received from the Tiantan Hospital Ethics Committee on the 29th November 2006 (ref: 7).
Health condition(s) or problem(s) studied	Venous thromboembolism
Intervention	Group A: stroke inpatients with Deep Venous Thrombosis (DVT) during follow up Group B: stroke inpatients without DVT during follow up DVT will be determined by complete-comprehensive ultrasound sonography two weeks (14 ± 3 days) after stroke onset. Possible risk factors will be compared between group A and group B, these will include: 1. stroke subtype 2. NIHSS 3. Medical history 4. Complications 5. High Density Lipoprotein (HDL) 6. Low Density Lipoprotein (LDL) 7. Triglycerides (TG)
Intervention type	Other
Primary outcome measure	Incidence of Deep Venous Thrombosis after acute stroke in China, measured at two weeks (14 ± 3 days) after stroke onset.
Secondary outcome measures	Predict model of VTE in acute stroke in China, measured at two weeks (14 ± 3 days) after stroke onset.
Overall study start date	08/05/2007
Completion date	08/10/2007
