Input: We identified two trials of GCS that included 2615 patients and two small studies of IPC that included 177 patients. Overall, physical methods were not associated with a significant reduction in DVTs during the treatment period (odds ratio (OR) 0.85, 95% confidence interval (CI) 0.70 to 1.04) or deaths (OR 1.12, 95% CI 0.87 to 1.45). Use of GCS was not associated with any significant reduction in risk of DVT (OR 0.88, 95% CI 0.72 to 1.08) or death (OR 1.13, 95% CI 0.87 to 1.47) at the end of follow up. IPC was associated with a non-significant trend towards a lower risk of DVTs (OR 0.45, 95% CI 0.19 to 1.10) with no evidence of an effect on deaths (OR 1.04, 95% CI 0.37 to 2.89). Evidence from randomised trials does not support the routine use of GCS to reduce the risk of DVT after acute stroke. There is insufficient evidence to support the routine use of IPC to reduce the risk of DVT in acute stroke and further larger randomised studies of IPC are needed to reliably assess the balance of risks and benefits of this intervention.
Output:

We found two randomised trials of graduated compression stockings, involving 2615 participants, and two small trials of intermittent pneumatic compression involving 177 participants. Graduated compression stockings were no better than 'best medical treatment' in reducing the risk of DVT after stroke. Stockings caused more skin problems (for example ulcers and blisters) on the legs. Intermittent pneumatic compression appeared promising but was not proven to be definitely beneficial. The evidence does not support routine use of graduated compression stockings or intermittent pneumatic compression in patients with a recent stroke. The trials that are ongoing at present should provide reliable evidence on the benefits and harms of intermittent pneumatic compression.
