Is there a style for Cochrane Database of Systematic Reviews

I am using Endnote X4 but coudn’t find a style for Cocrhane review. The citation style in the main text is like (surname of the first author publication year; ), such as (Higgins 2011; Meadows 2009). Does anyone know any existing style that is similar to this?

Thanks!

I mean output style

The style might be Chicago (15th or 16th) “B” but hard to pinpoint without a same bibliography to see how the references are laid out.
