3 April 2008	Amended	Converted to new review format.
13 February 2008	New search has been performed	We updated the searches between November and December 2007. The previous version of the review considered all studies where temperature‐lowering therapy was applied within two weeks of stroke onset. For the current version, temperature‐lowering therapy had to be started within 24 hours after symptom onset. The previous version of this review had no included trials. In this update we have included eight trials with 423 participants. The review has been updated and edited extensively throughout; the conclusions have not changed.
