What data we collect and how we use cookies

When you view our web pages, we may collect non-personally-identifiable information about your visit, such as your computer’s IP address and pages you visit. Such information may be stored on our servers, or in a ‘cookie’ on your computer, and is used for statistical purposes and to better personalize your subsequent visits to our site. If you enter your email address or password to enter a restricted zone of this site, that data is used ONLY to authenticate your access, and is not stored. If you fill in one or more of our feedback or service signup forms, the data you provide will be used as described in that form.

Cookies and the EU Cookie Law

A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer. For more information on cookies see the Wikipedia entry here.

Because of the EU Cookie Law and its implementation by the UK - as well as by other European countries - of the EU directive, we have to get visitors informed consent before placing a cookie on their machine.

We do use cookies to enhance users' experience. You can find more information about the individual cookies we use and the purposes for which we use them in the table below.

Please, note that by clicking on the 'Yes, I agree' button, you will give your consent to our use of cookies throughout all the Cochrane websites managed by us.
If, on the contrary, you'd like to disable cookies, since this action cannot be fulfilled remotely - that's also why a 'No, I don't agree' option is not available -, please see the help information contained in your browser or search Google for "How to disable cookies".
