While abstracting data on the extraction sheet. Should we have to copy and paste from the respective papers or we have to manipulate the data in our own words, particularly while documenting the result and discussion section?
Program RevMan for systematic reviews and meta-analysis can be downloaded from the website of Cochrane. This software has been developed by the Colaboración Cochrane. There is a link on the following web page:http://community.cochrane.org/tools/review-production-tools/revman-5
There is not a particular data extraction sheet to use in a systematic review or MA. You may find examples if you search the web. Happy to provide you examples if you don't find anything that fit your needs.
Ihsan Ullah Khan Altaf yes despite Cochrane you can also use Joanna Briggs Institute tools to perform a systematic review. Please see the link below for the JBI Manual :
